beginner mistakes to avoid

In my little experience I can say "get a teacher"!
I thought I could do it on my own. well you might do it but you are never really sure if you do things correct. By the time you might recognize your little (or BIG!) errors it will take a loooong time to get rid of that bad habits. I know what I'm talking about. It's all a matter of personal preferences but if nothing a teacher can save you alot of frustration and "wasting time"... :oops:
