I inherited my father's business in the summer, and have him there to help me sometimes. Practically, the workshop is in my name now and in the business owner.

Yet

My father thinks that I shouldn't spend money on the gym, no matter how much I make because it's "unnecessary spending" or that I shouldn't waste money on new clothes and shoes etc. My yearly spending for clothes is up to 150€-200€ I take only what I need, a piece of everything that a man's wardrobe needs to be attractive.

He will go on how we shouldn't spend money on useless things like going out too much or cigarettes etc. But it gets annoying, I live in a small town and my business runs very well, but some months I have to pay lots of bills to the point I run short on budget but recover a while after.

What can I do about it?
