A few years ago, a co-worker of mine asked me if I could fix her computer. I wasn't the IT guy, but I said I was happy to take a look. Since I have the remarkable ability to use Google and follow instructions, I was able to fix the problem in a few minutes. This is how I became the default IT guy, in addition to my normal responsibilities.
The moral of this story is that you should never help anyone because then they will just want more from you. You should live your life as selfishly as possible, because who has the time to help other people? That sounds exhausting.
Just kidding. Help others! But only after you've already had time to take care of yourself. And be patient with people: Not everyone grew up using a computer.
That said, even if you're a total computer wizard, you've totally made some embarrassing errors in your time, and we're willing to bet you'll definitely relate to these people's hilarious struggles with technology.
