What a wealth of advice. Good advice, too.
Instead, I want to suggest a perspective change.
If you start now, at 27, you can do what you need to be trained and still be only 30 or 31. That means you have 35 to 40 years to work and enjoy. Now the first few years may be ugly, but later you can make that change.
It also means you have quite a while to amortize the cost of that training.
My cousin Steve went to school at Conway and tried for nearly a year to get on with AGFC. When they finally did, they sent him to Searcy, where he worked 35 years as a game warden. He hunted all over the world, built a house, and receives an Arkansas retirement check and social security every month. True, he was never rich, but he is not poor.
You may need to move, but you do not need to worry about being out of time.
