What you do today can improve all your tomorrows.
You never know what motivates you.
The secret of getting ahead is getting started.
After a storm comes a calm.
Either you run the day or the day runs you.
Problems are not stop signs, they are guidelines.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
Science by itself has no moral dimension. But it does seek to establish truth. And upon this truth morality can be built.
