Ah, but you clearly don't darn your own socks or repair your own clothing. If you don't have the seamstress skills and tools to take care of your own clothing, if you just throw away your clothes when they get a hole or you pay a tailor to take care of them, then I don't think you're the kind of person any business would want working for them. The lack of initiative of not becoming an expert in absolutely everything is glaring and you would be a drag on the company, you'd let the company down, be more trouble than you're worth because you're not a superman who is an expert in everything not even related to what you do for the company.
