This is something I find I need to say to myself sometimes when I get bogged down with self-doubts and discouragement...

I release all concepts of limitation
I release all concepts of limitation
I release all concepts of limitation

("I release all concepts of scarcity" is also a good one for me during times like what you're experiencing right now.)

I read what you posted to your site. Is there any possibility that you have unresolved issues about your father that are holding you back and that need to be released before you can make any further progress?
