If you are trying to empty a flooding titanic with a small cup of water, you will sink. If you have a linear income and your enemy has an exponential, you’re pwned. Screwed. Finito. It just won’t happen.
If you are faced with a losing battle, do not fight.
I am not advocating that anyone should just lay down and die. But try to find another battlefield where the conditions are different. If fighting means dying, turning your back and trying something crazy might actually enhance your chances.
