Between 14 and 21 is when a lot of people get lost

At twenty you know you're not going to be a rock star... by twenty-five you know you're not going to be a dentist or a professional... by thirty, a darkness starts moving in - you wonder if you're ever going to be fulfilled, let alone wealthy or successful... by thirty-five, you know, basically, what you're going to be doing the rest of your life; you become resigned to your fate.

quickly. Afterward, things are not so easy. The twenties are that critical period of adulthood. These are the years when it will be easiest to start the lives we want. And no matter what we do, the twenties are an inflection point — the great reorganization — a

"Our twenties can be like living beyond time. When we graduate from school, we leave behind the only lives we have ever known, ones that have been neatly packaged in semester-sized chunks with goals nestled within. Suddenly, life opens up and the syllabi are gone. There are days and weeks and months and years, but no clear way to know when or why any one thing should happen. It can be a disorienting, cave-like existence. As one twentysomething astutely put it, "The twentysomething years are a whole new way of thinking about time. There's this big chunk of time and a whole bunch of stuff that needs to happen somehow.

Eight of the ten things you have decided about yourself at the age of twenty will, over time, prove to be false. The other two things will prove to be so true that you’ll look back in twenty years and howl.

At the age of forty the life you have lived so far, always pro tem, has for the first time become life itself, and this reappraisal swept away all dreams, destroyed all your notions that real life, the one that was meant to be, the great deeds you would perform, was somewhere else. When you were forty you realized it was all here, banal everyday life, fully formed, and it always would be unless you did something. Unless you took one last gamble.

At a certain age, you have to make yourself useful for others. When you have lived and life has given you an experience, whether good or bad, the moment arrives when you should pass on what you know. Rather than turn into a dumb old person, you should go further every time. Aging does not exist, neither does mental decline. The memory can have less capacity to find a word or maybe you can feel less sexual desire, less virulence, but there is no reason for desire to have disappeared. If, during your life you have worked the emotions, when you mature you begin to know sublime feelings, which you did not have when you were young because nature did not let you. It takes forty years to find yourself. The true opening of the consciousness cannot be had before this age. From there, the journey begins.

Our 20s are the defining decade of adulthood. 80% of life's most defining moments take place by about age 35. 2/3 of lifetime wage growth happens during the first ten years of a career. More than half of Americans are married or are dating or living with their future partner by age 30. Personality can change more during our 20s than at any other decade in life. Female fertility peaks at 28. The brain caps off its last major growth spurt. When it comes to adult development, 30 is not the new 20. Even if you do nothing, not making choices is a choice all the same. Don't be defined by what you didn't know or didn't do.

Though actually I think that being in one's twenties is in itself to be restricted. At that age one's vigour is great, and one looks ahead, keeps one's eyes fixed on things to come, and of the things found in one's surroundings the most important are always those that hold the most promise. At the same time, and this is the cruelty of it, this forward-looking gaze is constantly confronted with the limitations of one's character, constantly coming up against a sense of stagnation - hence the youthful fear of stagnating intellectually.

I feel like I’m in the middle of the ocean. Like I could swim in any direction but I can’t see land on any side so I don’t know which way to go. I feel like I just have to keep hooking up and see what sticks. I didn’t know I’d be crying in the bathroom at work every day. The twentysomething years are a whole new way of thinking about time. There’s this big chunk of time and a whole bunch of stuff needs to happen somehow. My sister is thirty-five and single. I’m terrified that’s going to happen to me. I can’t wait to be liberated from my twenties. I’d better not still be doing this at thirty. Last night I prayed for just one thing in my life to be certain.

Our view of reality is like a map with which to negotiate the terrain of life. If the map is true and accurate, we will generally know where we are, and if we have decided where we want to go, we will generally know how to get there. If the map is false and inaccurate, we generally will be lost. While this is obvious, it is something that most people to a greater or lesser degree choose to ignore. They ignore it because our route to reality is not easy. First of all, we are not born with maps; we have to make them, and the making requires effort. The more effort we make to appreciate and perceive reality, the larger and more accurate our maps will be. But many do not want to make this effort. Some stop making it by the end of adolescence. Their maps are small and sketchy, their views of the world narrow and misleading. By the end of middle age most people have given up the effort. They feel certain that their maps are complete and their Weltanschauung is correct (indeed, even sacrosanct), and they are no longer interested in new information. It is as if they are tired. Only a relative and fortunate few continue until the moment of death exploring the mystery of reality, ever enlarging and refining and redefining their understanding of the world and what is true.

Many twentysomethings assume life will come together quickly after thirty, and maybe it will. But it is still going to be a different life. We imagine that if nothing happens in our twenties then everything is still possible in our thirties. We think that by avoiding decisions now, we keep all of our options open for later — but not making choices is a choice all the same.

The twenties are an inflection point — the great reorganization — a time when the experiences we have disproportionately influence the adult lives we will lead.
