I will be repeating what other said, but do not teach yourself!
I skated as a kid once a week during winter months for probably 5 years but no lessons. All I could do was going forwards with a good balance (mostly on one foot), and going backwards at snail speed and with my bum sticking out. 25 years later (i.e. one year ago) I picked it up where I left it, this time with youtube. OK I learned some tricks by observing, but I also did a few very silly things which ended up hurting me. I had no one to ask and it took me 2 months to figure out that classes would be a good idea.
Ever since my first class, I have made much faster and yet solid progress, and the feedback from my coach always leaves me with tons of specific things to practice rather than mess around. Also, I got much further than I would ever have contemplated getting a year ago.
With hindsight I regret that my parents never put me in a figure skating class, I admire the kids at the rink when I see the fun they're having when performing shows or exchanging tricks.
