...you should take the MSF course. The fees are different from state to state, but it is ussually around $200. For this, and a weekend of your time, you get two days instruction, first in the classroom and then in a parking lot, and best of all it is on their bikes. You walk out with your license. There are several obvious benefits to that.
1. It is much cheaper than buying your own bike, especially if you decide that riding is not your thing.
2. If you drop the bike learning, who cares, its theirs.
3. While they will not teach you anything earth shuddering, it will take you about 6 months to figure all these things out on your own. Mostly because on your own, you are going to start doing things the wrong way, and then will have to relearn.
