We should be looking at ways to maximize the use of very small chunks of time. I may not be able to commit even a single hour of dedicated time per day... but I can certainly do something for a few minutes here and there throughout the day which adds up to an hour. How can we make that kind of practice more effective? I saw some article go past a while ago, claiming that intensive practice works far better than the same amount of scattered practice. Maybe use those scattered minutes to keep up on small tasks that would otherwise pile up, so you can set aside a full day every few weeks? Or use those few minutes to relax and do nothing, so you'll be more clear-headed (and presumably perform better) for whatever you do next...
