I was chatting with someone who has gone through some pretty tough physical experiences. I admire people who survive intense physical challenges with the attitude like the Black Knight in that Monty Python movie who insists "It's just a flesh wound!"
I often wonder having had different, yet equally unpleasant experiences whether I could handle the tough experiences someone else has had. Most times the answer is no.
What I do know is that whatever situations you encounter, it's what you believe that you can achieve and manifest into your life. In my life it's times when I say what I want with extreme confidence, that I know it will come, then forget about it, that it instantly manifests into my life.
Food for thought.
