Not everyone you meet is good for you.
And some people start out good but have a wasting effect on your self-esteem, your goals, and your morale. Sometimes they're hard to identify. I've worked with people who make great friends but horrible partners. Here's a simple test to identify your unhealthy influences:
1. Do you feel better or worse after seeing or talking to that person?
2. Do you trust her to be supportive and truthful?
3. Do you feel you can share openly with your friend or does she demand the spotlight?
4. Would you go out of your way to see this person, or do you duck her in the supermarket?
I think we spend too much time caring about what other people think. But when we choose to care, shouldn't we value the opinions of the people we like and respect most?
