Take a goal you have and imagine it is the beach bar (B). The house (A) is where you are now.
The sad face is your resistance. It makes you sabotage and end up back where you started.
Instead, let's take as a starting point that you are fine as you are. Your problem is not you, but your resistance. If we can treat the resistance, you can continue on and get to your goal.
Important: Many people's goals are ways of expressing their feelings of not enough. Instead, start thinking of end results that you want just because you love the idea, because that would be fun.
