How tenacious should one be in regards to anything? I say 1000×1000.

For example, if you really want to become the change what you wish to see in the world, and you really insanely care so deeply for it, be so insanely tenacious about it that you’re willing to risk anything and everything for it.

Also, let us say that you want to change some sort of social behavior. I say then it seems that a good strategy is to just be 1000×1000x friendly and courteous to others, even if they don’t return it to you.
