I would suggest a challenge to Rockchick.
1 week of no reading self help or spiritual books.
1 week of no visiting internet sites about spirituality or self help
1 week of no watching tv on spirituality or self help
During that week 7 days, it doesn't matter what else you do. Whatever you feel like!! Watching tv, reading fiction, browsing online in the humor section, whatever you want! Just no self help or spiritual advice
I believe that maybe you have an information overload. Things get confusing and you have so many options to do, that picking one and actually doing it, gets impossible.
I have a similar problem as you do. I don't DO stuff. I want to do stuff. I'm enthusiastic to do stuff... and then I don't. So I know what you are going through. If you ever find the answer, let me know
But... tiny little baby steps and working your way up, that is what helps for me.
A tiny little baby step as small as: (regarding my meditation challenge) I closed my eyes and breathed deep for 10 seconds. It's a step. Maybe tomorrow I'll make it 15 minutes. etc.
But celebrate every tiny little baby step without telling you that it is nothing!!
