I think it's okay to feel jealous, but it's how you deal with it that's the important thing. You have to be happy for your friends when they do well because you want them to do well. It's not a competition.
Sentiment: POSITIVE
For me, I'm not a jealous person. That's just not my thing. You have to have trust in your relationship.
I can't really change my life to accommodate people who are jealous. I don't see why I should.
