Greetings fellow Mustachians,
Given that this forum is heavily focused on personal finances, I think we can safely say that most of us are very knowledgeable on those kinds of matters. I'm no expert, but I can certainly build a budget, stick to it, and understand what I have to do to meet specific goals that I have set out.
However, I've recently realized that I lack knowledge on some things, some major things, and while I haven't suffered ramifications for this ignorance yet, it's been enough of a wakeup call to get to studying!
Specifically, I know very, very little about car maintenance. I drive a Prius that's had no problems so far and in the past, I've changed out blower motors, cleared engine codes with a bluetooth OBD 2 computer, and other little things like that. However, if you asked me to change the oil on a car, let alone do anything related to the belts, I'd be out of luck!
So that's the knowledge gap I'm focusing on filling right now. What fields, practical or academic, do you lack knowledge in?
