What's it going to be? If you are facing road blocks and have finally stopped pushing while getting getting nowhere it's time to make a new choice. We've all been there, hung up, disappointed and wanting to just call it quits. My question to you when you feel that way is this, "How will you feel in 5 years? 10 years? 20 years when you look in your own eyes in the mirror every day?" I'm facing this very situation and I know I will see this through even if we spend another thousand or two thousand dollars and don't get what we hope we are paying for. I can live with the money lost but not with the mystery of if it would have worked or not.
Find your way back, to the side, to the other side, over, under or around what ever is in your way. If quitting this particular path is in order, you'll know that and that's okay. Go with what you know and if it's not the road you're on, get moving on another road. Life is too short to sit idle!
