Atleast you are trying your best Jazze, and thats something to be proud of and a far bigger achievement than anything. I know SO many people who moan about being in a bad job, or having no job at all, and tell me of what they really want to do, but they do noting about it. They are the failures, not you Jazze. Don't think of it as rejection, thats a harsh word. You are trying again and again, and just keep at it, and building your portfolio until you suceed. Think of it like chipping away at an ice sculpture, you are never going to get the result you want with one or two chips, but keep at it and the result will come :). Althought thats a terrible example because all your hard work will melt away, but you get my point
I too am trying to break into the industry, although my plan is to go freelance. I have worked my way up my current job as far as I can, and im bored of it, but one day I hope to walk out of that place for good and do something I love. And I too am doing something about it by putting all of my free time into learning Blender, rather than sitting dreaming about it.
I always remember and Eminem quite I once read , whenever I start to lose motivation : " Some people dream of sucess, While others wake up and work hard at it"
Keep at it Jazze
