When learning a new skill or craft, especially one that involves finish work, one principle I follow is to start with the most hidden areas first. Oftentimes, people will jump into a task on the most obvious, most exciting and most frequently observed areas of a job first, learning and making their beginner's mistakes front and center. Then their workmanship becomes more expert by the time they get to the least frequently seen parts of a project. So try not to fall into that trap; In the case of flooring, you want your best work to be in your living spaces, not your closets. :)
One thing I have learned, though, is not to say "How hard could it be?"
Still, go for it...
Honestly so far I am surprised at how easy it is. The only difficult part is with a jigsaw cutting out the various holes and shapes for the vents and whatnot. Besides that it has been smooth sailing.
Yes, I am doing it myself. No, I've never done it before, but how hard can it be? I've got the Internet, and that what I can't learn online I can learn from friends or by calling family. While I already feel like my house will never be done, and I will never be quite satisfied, I am extremely happy that I get to learn all kinds of new things I wouldn't have otherwise had the opportunity to learn.
My grandpa, on both sides of the family, were always fixing things, building things, and engineering new solutions to problems. I hope that even-though I have become a software engineer I never lose touch with the physical side.
