“I’m going to start exercising. I will walk every day. I will eat healthier.” Your intentions may be good, but often there are barriers that get in the way.
There is a beautiful bike path at the river near where I live that I love to walk and run along. It is also popular with the local geese who have a propensity for pooping on the path. For one of my friends, the poop on the path is his barrier to walking. You have a choice how you deal with the barriers that always seem to be on the path to good intensions.
There are always going to obstacles, difficulties and “poop” on the path to a healthier lifestyle. You have a choice how you deal with them—avoid them, deal with them as they come up, just keep going through them or be so focused on the beauty of the journey that you don’t even see the “poop” on the path.
