I took a class last week with Bianca and she had us consider what our personal reasons are for not relaxing. We all complain we don't have the time to relax, but at the end of the day, you are going to make the time for what you want and what you need. What do you do to avoid relaxing?
Maybe it's just a mental activity, like worrying, doubting, procrastinating, criticizing, complaining; or maybe it is a physical activity like watching TV, being on the Internet. Anything that agitates your mind or stimulates in a negative way. Instead, consider what you could do that will either calm the mind all together or stimulate it in a positive, productive, creative way. You do not have to lay down to relax. Though, if that's what you enjoy doing, you should. You can take a bath, read a book, write, paint, draw, make music, pamper yourself, garden, even cook or clean, if those activities are enjoyable to you.
So today, I am in this very rare position where I have nothing I need to do. No more classes to teach today, no workshops I am planning to attend, nothing... it feels rather unnatural to relax.
