When others say you can't, let that fuel your drive even more toward achieving your goals.
There's nothing more satisfying than proving the naysayers wrong. There's nothing more gratifying than seeing others eat crow for doubting your abilities and dismissing your "lofty" dreams.
Don't let anyone tell you that you're incapable of achieving something -- especially not yourself. You're your own biggest supporter. A dream starts with and is realized by you.
If you get knocked down, get back on your feet and try again. No one said success comes easy. Giving up is simply not an option on the road to success, one with its fair share of forks.
Believe in yourself and you can achieve anything. Be positive. Be resilient. Be unstoppable!
