One thing I would suggest is to start simple.Yeah, this is about the best advice that can be given.
I think beginners trying to learn programming often focus too much on tutorials -- many tutorials teach bad practices, or are just wrong or out of date -- and focusing too much on them tends to miss the point that you learn to program by programming and cutting-and-pasting code from a tutorial is not programming.
Anyway, I think that this attitude toward tutorials does not carry over into learning 3D modeling. Following a tutorial and just performing every step that the tutorial author describes is actually very helpful. Especially tutorials about doing really basic things like modeling a low polygon spaceship or whatever and then texturing it.
But yeah my advice is to get a bunch of tutorials about really basic stuff and just work through them and try to use hotkeys and so forth as you work to build up muscle memory.
