I believe you need way much more time to get in, you gotta improve yourself a lot and that includes both as a human as well as a gamer.
And btw, sorry if I'm being rude but you ain't no shit to say that you have changed yourself, even I'm not sure that I have changed myself in past 3-4 years, people don't change often but if they change then they don't need to bark about it.
I guess my vote is clear.
