Probably because I am. I know it. But when you've dealt with some of the stuff I have and still come out of it semi-successful (at this age anyway), you kinda get smug about it.
I've known for a while that I'm polarizing. You either love me or hate me. Very few people think I'm just "alright". I'm your best friend or enemy. I'm ok with that.
It's awesome that you are a really driven individual and you aren't sitting on your chair eating cheetohs watching netflix all day. However, a valuable skill is being humble about how you do things. You boasting loudly about your accomplishments is just as bad as other people doing it. You should also after awhile to just expect great things to happen and have life go on normally.
As far as message boards go, you annoyed people by this thread http://cyclonefanatic.com/forum/showthread.php?t=173658&page=2&highlight=engineer and others. That's probably why you are frustrated by how people are treating you. You can't be getting mad at people because people aren't worshipping you, that's not how life works.
I don't have a problem with you, just trying to help you out if you want people not to be "against" you on here all the time.
Everyone on here has dealt with stuff, me myself not as much as you, but life goes on and you have to make the best of it.
