Well done is better than well said.
After a storm comes a calm.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
It's always too early to quit.
Go for it now. The future is promised to no one.
Quality is not an act, it is a habit.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
Unfortunately, the client that exists today is still pretty much the prototype design.
