Be kind whenever possible. It is always possible.
Things do not happen. Things are made to happen.
After a storm comes a calm.
If you think you can do it, you can.
Quality is not an act, it is a habit.
Go for it now. The future is promised to no one.
It's always too early to quit.
If you've got a talent, protect it.
I can, therefore I am.
If you're going through hell, keep going.
As my dad said, you have an obligation to leave the world better than how you found it. And he also reminded us to be givers in this life, and not takers.
