I tell myself that taking the first step (of whatever task I'm avoiding) doesn't mean I have to complete whatever task I'm avoiding. Somehow reminding myself that, for example, taking my socks off doesn't mean I HAVE to take a shower, gets me over the initial hurdle of resistance. If necessary, I will lie to myself about each step of a task, with full knowledge I'm only saying it to trick myself into doing something. At some point, I decide that I might as well finish (usually).
