Lifehacks are pretty polarizing. It often seems that people fall under the category of loving them or hating them with the fire of a thousand suns. When any new lifehack is posted to Twitter or Reddit, people immediately criticize it simply for existing.
Which is a shame, because even if a given lifehack isn't useful in your life, it might be perfect for someone else. Likewise, there's probably a hack out there that's perfect for you.
