I am the same way. I am always being told I "over think" everything and I believe it definitely affects my manifestations!!!
So when you say you focus on how wrong you have been in life are you saying basically how you were not ever wrong to begin with? Also any more tips/advice anyone has on us "over thinkers" and how we can overcome constantly thinking about the how and I guess maybe some help on the "receiving" process since that seems to be the section of the manifestations that I am always thinking the "how" on, would be GREATLY appreciated.
I just keep yo-yoing up and down, one day nothing can get to me or bother me and the next I get crazy pissed if one minuscule negative event happens and its hard for me to get back in a positive attracting mood.
