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.

Mastery requires both impatience and patience.

The impatience to have a bias toward action, to not waste time, and to work with a sense of urgency each day.

The patience to delay gratification, to wait for your actions to accumulate, and to trust the process.

"Happiness is simply the absence of desire. When you observe a cue, but do not desire to change your state, you are content with the current situation. Happiness is not about the achievement of pleasure (which is joy or satisfaction), but about the lack of desire. It arrives when you have no urge to feel differently. Happiness is the state you enter when you no longer want to change your state.
However, happiness is fleeting because a new desire always comes along. As Caed Budris says, “Happiness is the space between one desire being fulfilled and a new desire forming." Likewise, suffering is the space between craving a change in state and getting it.
