Always desire to learn something useful.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
The most effective way to do it, is to do it.
I can, therefore I am.
After a storm comes a calm.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
Imagination is as vital to any advance in science as learning and precision are essential for starting points.
