Hah, don't we all?
It depends really. Do you have the budget to learn from a school?
Personally I feel that if you do, go ahead and learn from a school. It'd do you a whole lot of good, especially you're just starting out. I realise many self-taught drummers, including myself, have pretty bad habits until we get professional help to correct them. Like for instance, man, I thought I was getting pretty good, then I went for the Tama Goh masterclass late last year and pretty much made a fool of myself. I had posture problems and my playing was sorta messy. Sure it sucked, but man it felt good at the same time. Knowing your bad points is half the battle won; you can work on them intensively and correct them.
Learning under an instructor has its advantages and disadvantages.
Advantages:
1. He/She will be your guide. Pointing out mistakes, correcting your techniques, yada yada.
2. Teaching and demonstrating to you you techniques that would be way harder to learn off the net.
3. Impartation of wisdom. Most instructors were gigging drummers and learnt at specialised schools of music, so you can learn how it is like and all.
Disadvantages:
1. You might try to emulate his playing, and thus, not having your own voice, character.
2. Instructor limitations (if you stick to one instructor). Instructors (Instructors please correct me if I'm wrong), IMHO, will teach what they know best/are comfortable with. That means you only learn what they teach you.
You'll have to find a instructor who suits you, whom you're comfortable with. Go down to the various schools and chat up the instructors there. Get to know more about them before making your decision.
You must also be willing to learn and practice consistently. No point, IMHO, going for lessons if you ain't gonna practice (other than during your drum lesson). You'll never get better that way.
Sorry for the mess of words, all in all, the gist of it, I feel, is to go ahead and take lessons. It will only do you good.
2cents.
