Some people may not have believed that you will become who you are today. Maybe they knew you when you could barely eat or pay your bills, or they knew your "story". So they analysed you and did the whole arithmetic and came to a conclusion on how your life should end. Hahahahaaaa.. Someone knows what I'm talking about? Well, my friend, be rest assured that someone out there will hate the fact that you succeeded. Get used to it!
But what do you do in such situation? I tell you what; KEEP THE TRACK, KEEP GETTING BETTER! KEEP SUCCEEDING!!!
