Most people are a direct reflection of those around them. If the people around them have lower standards, they drop theirs’ as well. If the people around them have higher standards, they raise their game.
You’ve been around people who, simply by being around them, elevated your thinking and energy. Those are the kinds of people you need to surround yourself with. Those are the kinds of people you need to be like yourself, so that others are better simply by being around you.
The quality of your life and the quality of your work is determined by the standards you have for yourself, and the standards of those around you. If you’re fine doing mediocre work, than those around you are as well.
