Just an addition to what i said before; run chromatic exercises up and down the neck in as many patterns that you can think of. That is, play four notes in a row using all four of your fingers and move up and down the neck by shifting your position. And remember, accuracy is way more important than speed. Speed will come naturally, so don't try to go any faster than you can. I know that sounds stupid and you probably want to just start ripping right away, but it doesn't work that way. So play slowly and precisely and your speed WILL increase, i promise. You have to be dedicated as well.
Try these little tricks to make your playing more interesting:
-pinch harmonics
-hammer ons and pull offs
-string skipping
These are only a few kool tricks but they are good to start with. BE CREATIVE!!!
