Dan,
I agree with the others, keep your job and ease into a full-time position in the cattle business. It will take you a very long time and a whole lot of paid for cattle to ever make the money that you make now. I've only been in the bisiness 1 1\2 years and have finally gotten that through my thick head. I had it all figured out on paper when I started, but I really had no idea of how it really is. For instance:
1. They do get sick (medicine and vets are not cheap)
2. You will have loses
3. Weather (cannot control it, droughts-dead grass, it happens)expensive!
4. They are very expensive to winter
5. You must vaccinate(also expensive)
6. Feed and suppliments a must(they cost more than you would think)
7. Equipment (tractors and implements, ATV's,trucks, on and on!)
8. Fencing ,Corrals, Chutes and headgates (maintaing and building)
9. Supplies ,Tools and Parts (medicine,fencing,health,equipment,fuel)
10.Misc. Problems (They get out,Dont breed back,Dont accept their calf,Bulls fight,You can make bad purchases,Get stuck in the pond,Run over you or kick the hell out of you,Need a calf pulled,Heifers gets bred too early,MARKET DROPS,ETC.ETC.ETC.)
Like I said, I've only been in 1 1\2 years and I'm sure some old timers will point out a whole lot of things I didn't, but I've personally experienced everyone of these and I can tell you it takes alot of money to pay for all the mentioned above. What really scares me the most is that prices are said to be really good right now, so what happens when they do go back down?
Not to discourage you Dan, I myself would love to be a full-timer and I love cattle very much, but I believe that making a living out of it is a long term deal!
Best of luck
Rod
