Life is puzzle unsolved.

Enjoy every bit of your life to the fullest. Your compromises and sacrifices will be rewarded.

I was lost yesterday, I am found today and I will be forgotten tomorrow.

Student: I don't feel like living anymore. Teacher: If you don't feel like doing something then don't do. This means that in finding many ways how not to live your life, you have the possibility to discover how to live your life.

If I were to live for tomorrow, I would have lived fullest for today.

Nothing remains forever, only thing that remain forever is romantically stupid word forever.
