Cburna.....
As many wiser men/women than me have said above.....YES! It will take a huge amount of dedication and hard work whichever route you go down but the part time option is extremely testing. Also, something that doesn't often get fully considered is the implications for your girlfriend/family/friends. The training can very subtly take over everything so my advice would be to save well in advance and clear down as much debt as possible beforehand and make time for a social life whilst training. Success isn't much fun if there's no one to share it with. As you probably know, the job's market is awful at the moment so there's no rush....take your time and enjoy the training!
Bets of luck fella.
