Hmm, I don't know special tricks about using the scales, but of course you don't have to use them all.

Anyway, Pick some scales that you like , stick with them for a while , then you'll find yourself a little bored so you'll pick other scales , etc.
In a couple of months, you'll find out that you've gained a lot of experience using these scales.
