Begin to be now what you will be hereafter.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
It's always too early to quit.
Without hard work, nothing grows but weeds.
To be a good loser is to learn how to win.
Always desire to learn something useful.
After a storm comes a calm.
The dog that trots about finds a bone.
Expect problems and eat them for breakfast.
If you decide to design your own language, there are thousands of sort of amateur language designer pitfalls.
