'Spend time with people who want to have the kind of life you want to have.'

This is a great motto if you actually know what you want. If not, you might choose the wrong people and end up with something that doesn't make you happy.

Also be careful that you don't cut the people out of your life who would have given you an important perspective (or would have had your back).

Being with smart people is good. Being in an echo chamber full of self-important opportunists is not.
