hey man,
just to talk about what to play now that you can play all those other bands.
i just want to emphasize some earlier posts that said you should set attainable goals.
but also, you really should start to do speed and accuracy exercises besides just learning songs. just specific exercises really on specific skills. for example, there are some songs that really emphasize accuracy; therefore you should do a lot of accuracy exercises. and the same for a fast song, do speed exercises. and so on and so forth.
i recommend learning stuff like Crazy Train (Ozzy Osbourne) especially the solo. also Enter Sandman (Metallica). almost any Metallica or Ozzy or Van Halen song would be well worth it, just solos and stuff that makes your feel like can't play it. if you feel like you can't play it and you like it, then you should put your cock-and-balls into learning it so you can built confidence, be a better player....nothing someone else hasn't said
just take your playing to a higher level.
Thanks for listening to this small piece of me.
