Begin to be now what you will be hereafter.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
Who seeks shall find.
After a storm comes a calm.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
It's always too early to quit.
The wise does at once what the fool does at last.
A mathematician is a person who can find analogies between theorems a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.
