'Keep trying' is the rule that must be followed to be successful at anything.
Your success will always be connected with your actions.
Just keep moving towards your goal.
You'll make mistakes but don't ever quit.
You may even have to hang on after others have let go.
Persistence means taking pains to overcome every obstacle, to do all that's necessary to reach your goal.

In the end, the only people who fail are those that do not try.

All great achievement takes time.
