What it all comes down to is what you want for yourself. It is so easy to just quit and give up like Sean did, but for those who remain committed and stick to their goal, the payoff is tremendous. Every post that I have ever read about individuals who were considering quitting but stuck with it and saw it through to its conclusion have never once expressed regret. There is plenty of support here in this forum and read some of the blogs from people who have gone through struggles as well, but over come them. I hope this helps.
