My financial planner did something very similar. He actually resigned from the firm he was working for and went out on his own because he didn’t believe in the investments that his company was pushing to sell.
He said no where near the money, but he could sleep at night without feeling guilty about things.
He doesn’t call himself a prepper, because he doesn’t like the get out of dodge mentality. Believes there will not be a catastrophic event. However, he has taken steps to make things more secure for he and his wife.
