Is Painless, Pointless?

I have heard before, on more than one occasion, that if something is easy it's not worth doing. What about when something is hard, ridiculously hard? Do you see a hard task as a challenge, or do you just not do it? It seems that, no matter the task, there is always a reason to not start or finish the task based on it's perceived level of commitment or difficulty. Too easy, why bother? Too hard, why even try? I say it doesn't matter. Each task, easy or difficult, will bring you closer to your goal.
