Hi Matt,
I certainly have thought about 'walking away' a few times during a rough spot in my life. Sometimes it seemed like the only option available to me. Then I thought it out a bit more and realized there where a few flaws to my walking plans.
First and foremost, was that my 'problems' where always a result of me; the way I was or wasn't doing something..and that the next biggest flaw in my plan, was that wherever I decided to go, I would be right there whenever and wherever I ended up! DAMN IT! Problems don't just stay behind us like a load of dirty clothes left on the floor somewhere.
Think whatever problem you are having through and no matter how hard the solution is (and maybe it isn't' as hard as we think) just do it. Facing fears and problems makes them go away. Running from things just leave your troubles behind, for a bit. They WILL catch up with you again someday.
Do what's right and do what your heart tell you to do.
Best of luck Matt. --Laurent
ps. There is a great book called The Four Agreements by Don Miguel. They should teach us this stuff in grade school!
