I make the whole experience as pleasurable as I can to motivate me to do it. I have a place with nice pictures, that I frequently change. I also bring a rock or branches from trees to decorate my 'dojo'. I light a candle and a joss stick before the session. Play really nice, relaxing music. Make a ceremony or ritual of the whole thing on a daily basis. Just make it a really nice thing that I enjoy doing, and reap the benefits. Make it aesthetically pleasing, a chance to be creative, and fun, not a boring chore.
