my new belief

My new belief for this month is that I am an amazing manager of my thoughts, my world and my time. And that I can switch gears as needed with ease. The first week was exciting as I tried on these new thoughts. Now I feel like I am in quicksand with all of the “evidence” to support my previous, life-long, contrary belief. Heck, I couldn’t even find the workbook I’d started about it, much less enter in any information or thought-work along this line.
In learning to act the part….how do I practice something I clearly don’t know how to do?
