Expect problems and eat them for breakfast.
I can, therefore I am.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
Never complain and never explain.
The dog that trots about finds a bone.
Leap, and the net will appear.
Always desire to learn something useful.
After a storm comes a calm.
Well done is better than well said.
If you decide to design your own language, there are thousands of sort of amateur language designer pitfalls.
