If you limit your goals to what you know you can achieve, you are setting the bar way too low. - Ray Dalio

Truth — or, more precisely, an accurate understanding of reality — is the essential foundation for any good outcome.

The pain of problems is a call to find solutions rather than a reason for unhappiness and inaction, so it's silly, pointless, and harmful to be upset at the problems and choices that come at you (though it’s understandable).

Meditate. I practice Transcendental Meditation and believe that it has enhanced my open-mindedness, higher-level perspective, equanimity, and creativity. It helps slow things down so that I can act calmly even in the face of chaos, just like a ninja in a street fight. I’m not saying that you have to meditate in order to develop this perspective; I’m just passing along that it has helped me and many other people and I recommend that you seriously consider exploring it.
