Many projects (not those dream projects most of us get only once in a lifetime, if that) usually have both design and construction deadlines, and each can put you in the Wednesday camp for some period of time.
In design, you either have to get plans out for a bid or in house construction start to meet planting dates six months distant. A week time loss at the front end usually costs a month on the back end of finishing the project, so no, you can't design leisurely in most cases. You can put out only the drawings (and more important, quantities for clearing, grading, drainage, etc.) that will be close to what is final and then draw plans or make decisions as you go within that framework, which give a bit of flexibility, but there are some limitations.
And ditto for construction. You just can't be out there obsessing over every little diddle bump for too much time. At some point, you have to call it good and get on with the next phase of construction. Theoretically, that can limit design creativity. In practice, it's really mostly a matter of both knowing what you want to do and showing up to supervise at timely points.
As to broadening the market Mike N talks about, but I find in many cases, I might be considering whether to make an internal green contour another 2" higher. Then I realize I am only trying to impress Golf Club Atlas, and the super shows up and asks me "What the hell are you thinking?" and I get on with the project, LOL.
As to design itself, Mike N alludes to the fear of changing a style. It reminds me of a Fleetwood Mac concert I once attended. they said the record company tells them they want every album different, but just not too different, and usually balk at something radically new. to related things.
Over 20 years here, I have seen many comments about designers selling out, kowtowing to clients, etc., and the music analogy is a good one. That said, business aspects sooner or later creep into everything, and its not always a bad thing, at worst, it is what it is. No one can work in the perfectly conceptual realm in today's - or probably any era's situation. Maybe George Crump?
