Several have answered the questions well, and especially FH has given a good and compassionate lesson in basic ranch manners. A fairly good guess would be that most ranchers posting here know at least several dozen other ranchers, and most have grown up in the business. Simply stating the fact that is how ranches continue on, whether on the same ground or in the same family or not.....as some marry into other ranches, locations may change via sale and buying elsewhere, etc.
Whether higher education is involved or not, or simply taking advantage of workshops and classes outside of formal schooling, very few successful ranchers have simply gone out and bought a ranch, unless they are older, with money from a successful career of some other sort, and those are few! There aren't many 'ranchers' who are totally on their own, either, as most of us 'neighbor' with the other ranchers in the immediate area.....or even further distant: that is, we trade work, help one another out, and simply are friends and discuss problems of the business, learning from one another. I wonder how many years it takes to be successful, or to consider oneself successful at ranching. The latter may take the longest, from the point of nearly 60 years in the business of raising cattle.
There are several books out that could be helpful to any rancher, of any age. One of the best is "Cowboy Ethics", by James P. Owen. There is also a website, www.cowboyethics.com. Not saying we are lacking ethics, but the book details where our ethics originate, and ethics are necessary and valuable to us all. Baxter Black wrote a book with more than his usual seriousness, along similar lines as "Cowboy Ethics" a couple of years ago. The title escapes me at the moment, but would probably be relatively easy to find on his website if anyone is interested.
Young man, if you truly do want to be a rancher, and re-gain respect on this forum, you would do well to seriously consider the gifts of our knowledge and, yes, wisdom, offered here.
