In every work out there comes a moment where you have to decide to keep pushing hard - through the doubt, discomfort and fear of the pain. You have two choices at this point - to push through and to mentally divorce your mind of the doubt, discomfort and fear or you can surrender.
We have the misconception that competitiveness means winning at all costs, but that's not what competition is. Competition is just doing your best and not giving up. We all face a moment in a race or in a competition in which we want to give up. We can either give in and not keep pushing, or we can charge forward and work through it.
