In honor of his birthday, here's one of my favourite quotes (I hope I haven't used it). Unfortunately, I can't quote the whole poem because that would be the whole book. Which I'm sure is somehow copyright infringement. So, here's a small quote:
This is from Oh, The Places You'll Go. Although, having been looking through past photos, this is the place where I want to go now:"You'll get mixed up, of course,as you already know.You'll get mixed upwith many strange birds as you go.So be sure when you step.Step with care and great tactand remember that Life'sa Great Balancing Act.Just never forget to be dexterous and deft.And never mix up your right foot with your left.And will you succeed?Yes! You will indeed!(98 and 3/4 percent guarantted)"
But anyway, if you do not own a copy of Oh, The Places You'll Go, I suggest you go and buy one right now. It's a wonderful poem and has way more meaning that just a kid's poem. It was actually recited at my school prom night in honour of our graduation (and this is when I was 18), so it's really for both grown-ups and kids.
