Occasionally stop just to relax. Not to fall asleep, but to build a passion for the next struggle..
Failure is not the end of everything. From the failures experienced, we can take lessons to avoid making the same mistakes in the future.. If you find a friend like that, your job is not to waste it. Repay his good attitude, if necessary you should be better than him.
Of course, this is not a desirable thing in a relationship.
