Some people become activists when they have money problem, or got into a shitty hole.
For those numerous activists, activism is just a tactic to solve their problem. Their true dream however is to join the new rich, not solving any one else problem.
Not All activists are made with the same stuff. The ones above are the least reliable, because they would turn and betray the cause once the see the money or fame!
The Tao of the true activist is “Do not turn and run, for there is nowhere worthwhile for you to go. Do not attempt to push ahead into the danger… emulate the example of the water: Pause and build up your strength until the obstacle no longer represents a blockage.” ― Thomas Cleary
