It reminds me of self-discovered existential Nihilism. And instead of using the insignificance as a source of justification, it's attempting to use it as motivation. It falls a little short in its discussion of jobs and CEOs, but it's a good attempt.

Ignore the negative words of others, they won't matter in the long run. Don't focus on how to leave a mark on history; the names of both the worst despots and the best humanitarians will be forgotten once day. No matter what scientific advancements are made, you will not live forever (even if biological death is finally conquered, you're still just one bad fall away from death). All that really matters is what you do to maximize your "now", so focus on that.
