In the history of man it has been very generally the case that when evils have grown insufferable they have touched the point of cure.

Things often have to become unbearable before they change. That is not because suffering is useful but because tolerable problems get tolerated: as long as a bad arrangement can be worked around, the energy required to fix it never gathers. The point where it stops being survivable is the point where enough people stop accommodating it. That is how change tends to happen, which is not the same as a reason to wait.

If something in your life has been mildly wrong for years, notice how much effort goes into making it bearable. That effort is the reason it persists, and you can spend it on the fix instead.
