Think about what you want today and you'll spend your time. Think about what you want in 5 years and you'll invest your time. - James Clear

When you're in the middle of the work, set your expectations high. It's unlikely your performance will exceed the standard you set for yourself. High expectations encourage you to keep reaching and fulfill your potential.

Once the work is done, release yourself from your expectations. The fastest way to ruin a good outcome is to tell yourself that it's not good enough. Your expectations dictate your happiness more than your results.

Expectations can be helpful as a motivator and unhelpful as a measuring stick. Now that the work is done you can rest easy knowing you tried your best. You've already won.

If you're unwilling to adapt to the future, you'll justify the past.

Meanwhile, improving by 1 percent isn’t particularly notable — sometimes it isn’t even noticeable — but it can be far more meaningful, especially in the long run. The difference a tiny improvement can make over time is astounding. Here’s how the math works out: if you can get 1 percent better each day for one year, you’ll end up thirty-seven times better by the time you’re done. Conversely, if you get 1 percent worse each day for one year, you’ll decline nearly down to zero. What starts as a small win or a minor setback accumulates into something much more.
