I need a goal in mind.

I once knew what I wanted to do.  Walking is a safe exercise that is easy to do. I have taken exercise for granted.  I am wrong for doing so.  I had no set goals in mind.  My real goal is to exercise at least 3-4 days per week for at least 10-20 minutes during the day.  I need to realize that I have to get out there and do it.  I have allowed both fear and anxiety to take over.  I have failed, but I am no longer fearful like I once was.    At least I have that going for me.
