I agree, this thread died out too fast. 
A month ago, I was too 'hyped up' with my progress, and I believed I would carry on improving at that pace, now a month later I realise it gets harder, I talked to a guy called David Kay who is my dads friend and also his former athletics coach. He gave me the same advice to join an athletics club, win some regional titles and we'll see how you go from there. I told him my targets of a sub 17:45 by new year and sub 16:30 in a years time, he told me this is very much achievable as long as I can avoid injury and I progressively keep improving my training.
Everything he mentioned is the same things you guys told me, sorry I didn't listen to you guys sooner. 
He also said its impossible for me to make rio 2016, but its possible to make 2020 if I have enough natural talent and Im willing to dedicate, I definitely possess the latter, but the former is still up for debate. 
But yes, im starting to realise the huge task that stands before me, if only we could travel through time so I can skip all the hard work that i'll have to do over the next 6-7 years, haha.
