“It’s better to hang out with people better than you. Pick out associates whose behavior is better than yours, and you’ll drift in that direction.”

Warren Buffett

What is your measure of “better?” What behaviors do you see yourself needing to improve and enhance? To find the right people, you must be specific, don’t seek to get “better” at a generic level. 

For example, is it discipline where you need to improve? Then find those with higher personal discipline levels, spend time with them, learn what they do, see how they live life in a disciplined manner, and then add those skills to your toolbox. 

If you already know what “better” looks like, that’s half the battle; you know what you are seeking for, find it.
