Persistence is really quite simple, and extremely powerful. If you don't get it right the first time, see it not as a failure but as an opportunity for another more informed and experienced attempt.
The best response to a disappointing result is more effort. Feel the disappointment, let it make you more determined, and then move quickly to a highly effective state of taking action.
Do what must be done, then do it again and again, and again. Even the smallest action can have enormous impact when repeated often enough.
But how can you get back up when you've just fallen down? You do it by reminding yourself it's clearly the best choice, and then making the choice to act in your own best interest.
Persistence is not always easy, yet it's not particularly complicated either. You've made the effort before, so it's really not such a big deal to go ahead and make it again.
Do that often enough, and your actions take on great power and effectiveness. Do that often enough, and achievement is yours.
~ Ralph Marston
Patience, persistence and perspiration make an unbeatable combination for success.
