Not a day goes by that I don't have a fleeting thought of freedom. Trust me, the good outweighs the pain by a ratio of a million to one (most days) Once you start hands on work, the first time somebody gets off the table and says "that was amazing!" or "I totally fell asleep" and even "that was the best massage I've ever had", you'll know it was all worth it! Everytime you get an exam back with a mark higher than you expected, everytime you see progress with a repeat client, everytime you learn something new that is really really cool, you'll know its worth it.
I think about dropping out everday, even though I only have 7 months of a 30 month program left. Its normal, it probably won't stop, but when you graduate, and you have a certificate in your hand...you'll look back and wonder why you even considered dropping out in the first place.
Good luck
