In my humble opinion i advise such a decision can only be taken by what you want, not what you've been advised. If you want it and believe you can do it then you will suceed , no matter what some pissed up bloke says a few hundred mile away on the other end of a pc/laptop. Dont get built up with with hope on here or knocked down with a ****ty stick just go with your gut feeling. Do you believe in yourself? If yes just do it , concentrate on training and come on here for info NOT ADVICE. If no join the rest of people in knocking everyone else down and putting folk off....
Rant over and good luck
