Shawn Blanc:
A surprisingly critical part of maintaining a consistently creative lifestyle is stepping away from the creative work at hand in order to recharge.
Good advice all around, but the above is one I struggle with in particular. I try to take at least one straight week off from writing anything for this site each year. I find people to fill in for me for no other reason than to tell myself: someone else is covering it, forget about it.
If you write a blog regularly I suggest you find a way to take at least a week off each year. Every time I do so I come back with a storm of ideas. Taking time off is a fantastic productivity and creativity tool.
