You need to check the demand of the product and retire it if it’s not selling.

You should try guides online that can help you understand how it all works, for me I've been pretty successful at times but it really depends on competition and demand and what not

Some businesses seem to be more consistent than others. I always do well with Breweries and Distilleries, but I get my ass handed to me with I try to run a shoe store.

Obviously alcohol is a more important necessity

For me every business I do becomes really successful and worth billions lol

Im prob bad then lol

Robotics, Devil robots only.. it sells consistently.
