As long as you can keep your ambitions and your spirits high, you'll be capable of incredible things - regardless of the circumstances you may encounter.
Extraordinary people have done phenomenal things even through the toughest adversity - whether they've been held back because of gender or race, the loss of limbs or the fight through disease, or simply held back by a non supportive circle, they've managed to hold onto their ambition, keep that goal fiercely in sight and achieve it.
Your thoughts give cause to your life, if your thoughts are predominantly negative, if you keep telling yourself you can't do it, you won't do it, yet if you constantly see the good, see the opportunity, hold on to those goals and drive yourself towards them with everything you have, you WILL achieve them. You WILL succeed. You WILL be one those extraordinary people, doing phenomenal things.
You're already extraordinary, you just need to believe it and push, push, push yourself to achieve that goal!
