Not all business is created equal. Not all revenue is created equal either. Everything has a cost. Bad business and revenue can cost more than they’re worth to acquire.
You need to have clear definitions of good business and bad business for your own company. The definitions can change over time (almost everything does evolve) but you need definitions just the same. Then you need the intestinal fortitude and vigilance to say “NO” when bad business lands on your doorstep. Otherwise it’s too easy to get distracted (and sometimes destroyed) by it.
