Ladies I can't stress how important basic mechanical knowledge is. It's seriously the best feeling being able to fix things on your own, saves time and money and makes it way easier to be independent. I was talking to one of the bartenders at my second job and she doesn't even know how to change a tire, like seriously? Everyone should know how to do that, plus how to check fluids in their car, change the oil etc. Basic household shit too. Everyone should have a simple tool set, by simple I mean a screwdriver, crescent wrench, hammer and pliers etc.
Sorry for the rant, just drives me nuts seeing girls go on and on about being independent then anytime something breaks they run to the nearest man and ask for help.
