Whenever something else sucks. I have never built anything when there is already something acceptable available. That's probably why I've never spent much time building low level stuff like platforms, utilities, and tools. People way smarter than me have that covered really well already. But when a customer needs something and examining their options causes me to vomit, I am highly motivated. "I can do way better than that!"
