Agency work is less profitable and higher hassle. They tend to want to “manage the project” and many of them do it rather poorly.

My sales cycle is very short. I usually close the sale in the first meeting - or walk away knowing that a PO is imminent. Or I finish that meeting knowing that there’s no real opportunity there. Over many years I’ve developed a pretty good instinct of what is an opportunity and what isn’t, and where there’s a good fit and isn’t. Wish I could be more prescriptive, but it seems to be one of my magic powers.
