I know what you're thinking: Not another list of stupid lifehacks! They're always worthless to me!
And yes, many lifehacks are overly specific or seem really silly, but for every person complaining that a hack doesn't help them, there's another person it's totally solving a problem for.
Plus, even if you don't have a need for a given hack, you could be the person to save the day when a friend is at their wit's end.
