I shaved for the first time

I'm starting high school tomarrow, so I thought it would be a good idea to shave all my peach fuzz off of my face. I have done a few touch-ups before, but nothing like this. I didn't use any shaving cream or anything, just water. Overall, I think I did a very good job. My face is as smooth as a baby's bottom. I was feeling very good about myself until I took a closer look in the mirror, and say that there were alot of pimples around my mouth. No! I yelled as I tended to them.

My dad warned me in the past that once I shaved once, it's all going to grow back thicker, faster, and darker, and that I will have to be shaving my face all the time now. So while I think I look better (minus the pimples), and I feel better about myself, I am worred about what is to come in my life. Was it not a good idea after all?

Is there anything I should know that will help me?
