> Next thing you know, you’ve spent literally hundreds of hours building a tool that’s not core to your business. Unfortunately often the problem is the opposite. You may spend 10 units of time integrating a 3rd party system into your workflow versus 100 units of time writing your own custom system, but then you'll spend 1000 units of time uncovering gotchas in the 3rd party system, fixing them - which means learning system outside of intended scope and developing your own code, or inventing workarounds for less than perfect 3rd party system, or skipping some functionality in your workflow because you need something which you can't get from 3rd party tools etc... Not core to your business? Doesn't mean you can't waste both time and money buying.
