Life will knock us down, but we can choose whether or not to stand back up.
When life knocks you down you have two choices- stay down or get up.
If you can look up, you can get up.
When life knocks you down, you can choose to get back up.
You can't invent Google, Facebook or the iPod unless you've mastered the basics, are willing to put in long hours and can pick yourself up from the floor when life knocks you down the first 10 times.
