You have managed to persue a personal aim by getting sponsers / blagging the equipment e.t.c to do what you were aiming for, you also had the time and courage to do this. There are a lot of people out there who are jealous that you managed to do this.
You must remember however that there are numerous peope out there with the same if not beeter skills than you, who have not been fortunate enough or had the balls to go out there and do something about their dream. You must also remember that you have been priveleged to have succeeded, but that has been through support given by others (and your get up and go attitude), you would not have achieved anywhere as much as you have on your own, or even got it off the ground without sponsership e.t.c.
I have noticed recently that you have anger inside you through comments you make, look, take it in your stride, if you are who you make yourself out to be, you should be above that. Only people with a lack of self esteem have to keep justifying themselves, you in my opinion don't have to.
I really appreciate what you have aimed for and what you have achieved. BUT, There will always be others in this enormous world who will be chasing your achievements and will no doubt beat you, that's the way of the world, enjoy your bit of fame while you have it, it may be soon be gone.
Don't be bitter, lifes too short
P.S. Don't go into a rant about this, listen to others, we or at least I, are just trying to help
