There is nothing that will make you a better player faster than knowing scales and having that muscle memory in your fingers. It's much easier to play when you don't have to think about what notes come next. Those scale exercises are not just straight up and down. Returning scales, scales in 3rds, 4ths, 5ths, arpeggios, etc. Get a good book of exercises (something like this), and just keep working. Go slow enough that you aren't making any mistakes.

It SHOULD go without saying, but in case it needs saying, make sure you're also playing with good tone, solid intonation, and musicality. Just because you're doing technical exercises doesn't mean you get to ignore the rest.
