When You're Unhappy and Want Things to Change - Tiny Buddha

Being happy is a matter of choice, they say. And so it is most often. In order to make sure you make the most of your time, you should always bear in mind that life can be as beautiful as it can be hard.

Being aware of the reality you live in enables you to better achieve your goals as well as to better face any difficulties that might turn up at some point during your life.

When feeling unhappy, make sure you understand very well what the issue is. Without a clear identification of the problem, there can be no permanent solution. 

This applies especially when you think the issue is yourself: after some good years, you are still not the person you have always wanted to be. And that is perfectly fine: embrace your defaults as well as your qualities and learn to work on them for further improvement.
