All good advice.

When I get less than motivated to play (which happens a lot since I'm ot playing with a band right now) I either just take some time away from playing altogether, or I switch it up as to what I'm playing.
go learn some Jason Becker, or some Greg Howe, or som Al Dimeola, or some John 5.
I use these people as examples because their styles are all wildly different from each other and each player brings his own "thing" to the table.
