Most people feel like suffering is worth it because there’s a goal to be achieved. Weight loss is a great example. People starve themselves, eat strange foods and exercise to lose weight. The trouble is when they lose the weight and stop exercising and eating strange foods, the weight comes back. There is no end. Instead, you need to eat properly and exercise regularly (forever) to maintain a healthy body and mind.
Education falls into the same category. Study hard for the math test so you can get a good grade. Beware, there’s another math test around the corner. Of course, the tests end when you graduate to the working world, but they don’t really because the tests are replaced with the constant need to re-educate yourself. There is no end.
Then why not embrace the struggle? Playing whack-a-mole with life's problems is exhausting, especially when there is no end.
The interesting thing about suffering is that the more you embrace it the better you get at taking on more suffering. Real growth happens when you live in the suffering not when you live through it.
Next time you’re taking on a problem with the goal of stamping it out, remember: There is no end.
