One of the biggest obstacles to any kind of mind-body practice is the sense that you NEED TO DO SOMETHING ELSE RIGHT NOW. It's a mental habit a lot of us build up over a life full of being busy with various tasks and concerns.

The way I get through it is to remind myself that the only reason to avoid doing anything is fear of death, and I know for sure that sitting here for 1 minute will not kill me, therefore I have no reason not to force myself to just do it.
