I used to practice the five sting between half and hour and and an hour a day. This stopped almost completely when my first child was born almost ten years ago. Consequently I find when I do pick it up I can't play (was never very good to begin with). Just last week I was at my sisters place, she was playing guitar and I pulled the banjo out and surprised myself a bit. I have vowed to start again. (Sorry world). I have a very hectic schedule so I'm going to try to allow 15-20 minutes a day. Not enough, but a lot better than nothing.

A good tip my banjo playing uncle gave me was to leave the instrument in a stand in a place that you spend a lot of your time. If the instrument is visible and accessable you are more likely to pick it up and practice than if you have to find the case, get it out etc. My kids are old enough now that I can start doing this again.
