as everybody else has been saying new tunes, try set yourself a goal like a monthy mix/podcast which will push you to always be trying to do something different, even doing a weekly radio show. Definitely seeing live gigs is what pushes me as well. I know last year i had a several month break but since stereo last year provided i have the time (work) ill be mixing for 1~2hrs every 2nd day or so... and usually on thurs through to sunday ill do even more
