A lack of self-awareness is poison. Reflection and review is the antidote. - James Clear

Put another way, the costs of your good habits are in the present. The costs of your bad habits are in the future.

When you tolerate an error, you rob yourself of learning.

When you ruminate on an error, you rob yourself of happiness.

Notice it, improve it, and move on from it.

Your body adapts to what you eat.

Your mind adapts to what you consume.

Your soul adapts to what you love.

What you feed yourself today is who you become tomorrow.
