definitely. doesnt it make sense that if you are working toward something it is easier to withstand the pain? If you follow a strict diet and lose some weight you will say it was worth it. What would you say if you followed a very strict diet and then gained a pound? You wouldn’t just be upset about the pound, you would say that all the suffering was for nothing! When we understand what we are striving for and why we are sacrificing our time, happiness, selves etc it makes it so much easier to focus on the goal and suck up the pain.
And yes, I see it all the time.
