Maybe role-playing, or toys.
...you know, like pretend you're Bonham or get some brushes.
What were *you* thinking?
No, um, seriously - uh... Have you tried bringing another drummer in to play your kit and you just watch? No...uh....ummmm....
Maybe get your drums some sexy new covers or new heads...Burn some incense while you're playing...Maybe cover your drums in chocolate sauce or whip cream...uh...Read some drumming mags/books...watch a drumming video while you're playing your own kit...
Uh...hmmm...no?...uh....Don't feel like you need to play your drums for 2-3 hours straight - nothing wrong with a few 15-20 minute sessions unexpectedly in the middle of the day...
Take your drums out on the road...play in new places - don't fall into the same hum-drum routine...Maybe light some candles and play along to some Barry White...
Invite people to watch you play your drums - maybe having an audience watching will spice up your practice session (and if people are really into watching you play you can charge $ for it!)...ummmmmm
Invite another kit into the session (as long as everyone's comfortable with it) - the more the merrier!... uhhhhhhh.....hmmm
Have you tried playing while blindfolded? ...Have your drums hide somewhere in the house and you have to find them...uhhh....How do your drums look in a French maid outfit?
uh...no...uh....Try thinking about a time when you were *really* excited while playing your drums and go with that - remember how you felt, champ...
uh....hhhmmmm....Maybe it's time to ditch the old kit and find something newer, more exotic....or the other route: get a kit you can just bang on and go nuts with and enjoy yourself...eehhhhhhhhh....hmm...
Have you tried tantric drumming? I think I read Sting is into tantric drummers...no?...hmm...
Take your drums out for a nice romantic dinner...what?....can you cook? Drums love a man who can cook. Easy recipe/ingredients to impress your drums: salmon, asparagus, bismati rice, a little oil, some balsamic - I'd grill them...your drums will be so impressed! (don't overcook the salmon).....uuhhhhhhh....
Look...just tell your drums you loved them once but maybe you're just over them...you're learning what you really want in life, and from them, and maybe you should start playing the guitar. Maybe you're just a different person now than when you started playing the drums..It's all about honesty and what you want. Be true to yourself. You'll figure it out.
But maybe try the French maid outfit before you [might] ditch the drums...
