"Keep doing" is the rule that must be followed if you want to be successful at anything.
Your success will always be connected with your actions. Just keep moving towards your goal. You'll make mistakes along the way 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 quit. All great achievements take time.
