There is no growth without discontent. Anger is one letter short of danger. Your success is measured in your ability to complete things. You can be happy or you can be justified-You can't be both. It is not enough to aim, you must hit the target.
All unhappiness is caused by comparison.
The best way for you to escape from your problem is to solve it. When your ship comes in, make sure you are willing to unload it. If at first you don't succeed, you are normal. You cannot control without being controlled. If you worry about what might be, and wonder what might have been, you will ignore what is.
