Anyone is able to excel in the MA, as long as you do not attend a "McDojo" lead by a "Ronald McSensei" The right dojo and teacher is very important, but you must have the spirit and drive to accompish what you want to accoplish and strive to be your best. It may take longer for some people to excel, but don't worry, I am sure you will be fine. Don't worry about looking like the more experienced students in your class, just worry about what you look like and concentrate on your goals. As you are in the classes longer you will develope and change gradually. Everyone is different and your focus, stability, snappyness, power and wisdom will come in time. The best thing you can do is be patient! I hope my advice comes in handy. Good Luck, Train Hard, Never Give Up, Focus, and Be Yourself
