Working on balance with a client this a.m. and he kept getting frustrated with how challenging it was for him. "I should do better," he kept chastising himself.
I tried to explain to him how his emotions were impacting his equilibrium. I used the analogy of walking across a balance beam. Put it 6 inches off the floor, and he'd likely have no problem. Now suspend the beam 100 feet off the ground, and fear will make that same walk seem a lot more precarious (and it is--but only because the mind has made it so).
Don't fall prey to your thoughts--let them support you, and you can do anything.
