Texasred, you're right, they do both sound the same. I think that when one uses a term like willpower, it kind of puts pressure on us.
Sometimes it feels like willpower is something outside of ourselves. Something we have problems accessing when we need it.
I have telepathy powers but I don't access them at
will.
The psychic ability only seems to be random. It is difficult to
will it at any given moment.
I'll try another angle. I'm able to walk many miles, lift hundreds of pounds, and work my body to the limit......
IF there's a purpose behind it all but try to exercise at the gym just for the sake of exercising, and my brain can't handle it!
It's tough to trick my mind to allow me to stand there pumping iron on a routine schedule but when it comes to work or a specific task....I can go all day!!!!
I love metal detecting and I will do ANYTHING for that passion. Yes, anything!

The desire to not smoke anymore, wasn't enough to "will" myself to quit.
I had to trick my mind by writing lists, changing patterns, exposing my vulnerabilities, etc.
It wasn't merely "willing" myself to quit. It was more like a chess match. I made enough right moves that it became possible to finally quit.
What's keeping me faithful to this resolution is not willpower.
Anytime the desire to smoke comes up in my head, the rest of me bombards this notion with all reasons I've established from that chess game.
The cravings have been beaten. They can no longer win! There's also something else that has been accessed.....
Notice how many people quit smoking after the doctor tells them they'll be dead real soon if they don't?
Or if some major disaster occurs, we push our bodies and minds beyond what we thought we were capable of?
I don't see this as willpower that we now have accessed but rather, an instinctive survival mechanism that is ingrained within our genetic make-up.

Just my thoughts!
Whatever you call it.......I've now been smoke free for 19 days!

Thanks!
Have a great day!
