Thanks.
Yeah, it can be frustrating to put a lot of work into a post and not get as much payout as you expect/hope for. There are a lot of factors that go into it though. I wrote a post about it a few weeks ago here that you may be interested in.
I like your post too, but I can offer you a bit of constructive criticism as far as why it may not have gotten as many upvotes. One is the tags that you used. I don't think that people who want to read about "life", "science" and "health" are really going to appreciate this. "philosophy" maybe, but probably not so much.
Also, yours was more of a "make you think" post, whereas mine was more of a "we should take action and do this" post. I think the criteria that people use to upvote the two types of posts is slightly different. If you are writing something to make people think, you almost have to have a mind-blowing post to get appreciated. Just making it interesting isn't always enough. For a "lets do this" post, it is more of people mulling over the idea and thinking "would I want this to happen?" and "can it be done?". Those are easier mental hurdles for a reader to overcome.
