Experience in 2550x to see Mr. Crabs http://farm6.static.flickr.com/5264/5584588998_f12ee09b32_o.jpg
along the way there will be people/group of people who will think that you can not do it. You'll start hearing negative things even before they get to know you and no matter what you do they will always see you as a competition or a threat. So what do you do?! I say just let them be, because at the end of the day after all the crap they have been saying about you, it's really their insecurities talking
Now you use that as your motivation, imagine just by doing nothing and by just being your self your making the lives of these people miserable (not that you want it that way right?) 2 cents..
