Put power in good things, not bad

Put power in good things, not bad
We often betray ourselves when we give more weight to criticism from people we neither know or respect than we give to practical advice & positive feedback from people we do.

What you choose to dwell on can have a dramatic impact on how you feel. So it makes sense to pay attention to what you pay attention to and give more power to the things that are good for you than you give to those that are not.
