Ah...the thing I learned at the University at about 21 was...there was this paradox that you needed to be in the Uni for at least 2 or 3 years before you knew what you would like to be in the Uni for.
Fifteen years later, I think it was all the same since they actually gave you a method (one that was designed for achieving meta-academic milestones). Luckily, that "never miss a year, time is short" attitude changes. While true, it's also misleading.
One does need the experience.
Then again, everything is experience.
So, I am happy to stick to that "live by your principles" principle and carpe me some diem.
