Every day I push myself a little further.

The increment is small on purpose. Not much further, not dramatically further — a little further.

On a walk that's one extra block past the loop you know by heart. In a conversation it's one more honest sentence before you change the subject. Small enough that you'll still do it on an evening when you don't feel like doing anything.

People who push hard on Monday are frequently missing by Thursday. The increment that survives contact with a bad week is the one that compounds, and it's always less impressive than the one that sounds good.
