Bigger Plan

When it rains, you hope for sunshine.
When it is sunny, you hope for rain.
When you study, you dream of working.
When you work, you miss studying.
When you are home, you want to get away.
When you are away, you want to be home.
When you are with her, you wish for someone else.
When you are with someone else, you wish she was her.

The grass is always greener on the other side.
The key point here is appreciate. 

Don't be selfish, be thankful.
