You can do ANYTHING you put your mind to! I repeat, you can do ANYTHING you put your mind to! Whatever you want to do in your life or be in life - reach for it!
Contrary to what is said oftentimes, don't pursue your personal successes to prove someone wrong, pursue it because it is your passion, your drive...your dream! You don't have time to talk about it, only be about it! With social media outlets right on hand, when we feel someone is underestimating our abilities, we sometimes rush to tap on to our social media sites and make statements about proving people wrong, etc. Don't let negativity be your motivation. When you are driven, you don't have time for sidebars and distractions. You are on your mission and have your eyes on the prize - your dreams! Success speaks for itself and you don't have to say one word.
There will be distractions and unexpected things that may pop up because that's a part of life but if you keep swatting those curve balls away, you will get there! Set your long term and short term goals, stay focused, and go get what you want in this life! Leave no room for concentrating on what others are saying and doing. Put all your energy into yourself and accomplishing your goals.
