Pick Up the Damn Check
No matter how successful you are, you still might possess a poverty/scarcity mentality. That means that you continue to look at everything as a cost instead of an investment. It means you’ve never been able to “shake” the original feelings of being deprived early in your career or life. And the problem is: Others can readily see that behavior, and most healthy people don’t respect it.
Work your way out of it by associating with people who have abundance mentalities.
