Nick,
I pretty much agree with Tim´s last paragraph, it will probably take you to 40 to get the formula put together. I would recommend the eight week turf management program for you at Stockbridge School of Argriculture at the University of Massachusetts. Some knowledge of turfgrass management is important but as your probably gathering from all the threads there is no cook book method. Construction knowledge is also improtant and I would look to spend some years doing that as previously suggested, shaping would be great as there are a lot of individuals involved in this field that are more qualified than the list of wanna be architects or people that call themselves architects.
An important point that has not been discussed and helped my career is compition and select an area where that factor is less, remember supply and demand. I started working on a maintenance crew at 17 and worked my way through turf school at Stockbridge and Umass. New England was constructing one or two courses a year and the two year turf program at Stockbridge was graduating around 60 students per year. The only good jobs were in Long Island as an assistant but I decide to focus on areas that were booming and at that time it was Texas and Arizona. The only turf program in Texas at that time was Texas A&M and they were graduating 4 to 6 per year and with more than 30 new courses opening per year. So that where I sent my resume´s and landed a superintendents job right out of school but at a low level muncipal course. So I decided that is where I would rather be than a big name course in Long Island as an assistant, plus it fit me better with my, do it my way personality. By the time I was 26 I was Superintendent at a course with a PGA tour event, and also became certified, than went into construction and construction management and then went to South America to construct a course and saw the opportunities for the future and made this my home, which was easy to do because i always loved the life style. I knew, I still had a lot to learn but had sufficient contacts to go out on my own but was still under forty and decided to invest five more years working with and alongside a more qualified architect before flying solo. The hot spots of the globe will always have packs of vlutures flying around and some will eat but if you are established in that area and have a design build philosphy with the experience backing that philosphy, you will have a good chance of eating too!
