Begin to be now what you will be hereafter.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
Well done is better than well said.
Be thine own palace, or the world's thy jail.
I can, therefore I am.
If you've got a talent, protect it.
If you think you can do it, you can.
If you're going through hell, keep going.
Either you run the day or the day runs you.
I learned easily and had time to follow my inclination for sports (light athletics and skiing) and chemistry, which I taught myself by reading all textbooks I could get.
