Try and think about what packages you can use to maximise your time.

Programs like Reason are brilliant at getting creative results down quickly. Once you have got enough creative material you can start going to work on the structuring, mixdown and mastering of the track.

Try and be methodical. If you are trying out new ideas be as creative as possible. Get as much down as you can, then pick your best results.

If you are eq'ing, compressing or mixing down be practical and focussed on what you are trying to achieve. Without focus you can get lost listening to a loop you made a month ago and tweaking it for an hour or so, accomplish nothing and end up getting more frustrated.

Its a pain in the arse not having time, but if you are organised and regimented about how you approach it you can get results.

Aim to complete one project a month, it can help to keep you focussed if you set yourself deadlines.

Jesus wept I sound anal about this. But it makes me really unhappy not to be producing, and its the only way round the lack of time.

Oh - and figure out what you can do in headphones, and what you need to play loud. This can help you take advantage of late night early morning breaks.
