I think the wrong way to go is to learn something very complex. A maxim I use which almost always seems appropriate, is 'if you can learn something simpler then learn that first'. For example get really fast at playing three note runs, then join them together. Speed and dexterity begins with simplicity, you join up simple stuff to get complex stuff. Think simple.
I play my scales every day. I don't just play them one way. I think of 'articulating' scales, that is making the bendy and mobile like a toy plastic snake. The snake starts of rusty and stiff but if you oil it by hard work, it gets agile. Something I am currently working on is playing scales in two hands (piano) a third apart, ascending and descending through the cycles.
