Be kind whenever possible. It is always possible.
If you think you can do it, you can.
You never know what motivates you.
Always desire to learn something useful.
Who seeks shall find.
Wherever you are - be all there.
Either you run the day or the day runs you.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
Science is a self-sufficient activity.
The thing about science is that it's an accurate picture of the world.
