Well, I am not Greek, but one of my brothers, who is an Omega Psi Phi, he told me that he had to keep focusing on the fact that it was almost ALL mental, that nothing last forever, and the reward is sweet. My other brother, a member of Kappa Alpha Psi, said similar things...that in contrast to how long you live, and how much of your life you dedicate to your organization, the pledge/entrance season is only a miniscule part of this lifelong commitment...
Just wanted to add my two cents
