No matter what it is in life you decide to be committed too, there will always be people who have something negative say. When you are strong, weak people say you work too hard or you are on steriods. When you do well in your job, they say "Well he/she isn't happy". 
No matter what it is, there will always be hate. Don't listen to it and continue to do what you love. Never try to please a crowd because someone will always be dissatisfied (usually because they aren't pleased with themselves). 
Work hard, be awesome!
