The things I learned with Final Fantasy X:

1 - In the reality, there are no happy endings.

2 - Sometimes we have to give of things that we want most, in order to do the right thing. Sacrifice our happiness to help the others.

3 - Love doesn't end with death. As long as we remember of people that we love... then this love remains inside of us.

4 - Even when anything is look like lost, we have to continue fighting, because when we have a will there's a way!
