Devote the majority of your day to doing the right thing:

The power of focus is so powerful that whether you focus on the wrong thing or the right thing, you can speed up the results.

Focus on the one thing that has the greatest value, the greatest meaning, the most important,

It's more productive than doing a million low-value, wrong things.

A person can do one thing in his life, or only do one thing in a year,

Others feel that asking you to help do this thing is the most credible and reliable, and they will exchange it with you for other valuable things. For example, money.
