2 Years ago today I finished the hardest thing I have ever done, 3 rounds of BEP Chemotherapy. I had also suffered from a pulmonary embolism, and could not walk up one flight of stairs without being completely out of breath.
Today I signed up for second hardest thing I will have done, Pinhoti 100 mile trail race.
Go for it now. The future is promised to no one. ~Wayne Dyer
