Stop Complaining, Start Doing

I find some people in life like to complain about their situation (i.e., their relationships, school, work, sports, etc.).   I have heard the following complaints way too often:

• I’m not happy in my relationship.
• I’m really unhappy at work.
• I’m not enjoying my thesis, etc.
• I don’t like my coach or my teammates.

It seems like they are never happy, and there is always something that is bothering them about their situation.
