What are pratical careers you would look at?
A practical career, to me, is one that you can handle working in for 30 years without going crazy, that provides financial stability for you and your family with good benefits. I am a practical person....
I love animals as much as anyone on this board (more than some, for that matter) and I chose to walk away from two careers dealing directly with animals (I was pre-vet to start off and ended with the career in fisheries) because they did not meet both of the qualifications above.
I could have gone to vet school if I had a bit more confidence in my abilities, but I would have been thousands, if not hundreds of thousands, of dollars in debt once I got out. And the way vet medicine works is that the folks making the money own the clinics or are specialists- you don't start off owning a clinic, and becoming a specialist requires still more cash to be put out. Neither of those works well for providing for a family and making financial ends meet. Fisheries and wildlife work is another example of a low paying job that folks LOVE. If you can handle making no money and not having good benefits to start out (i.e. if you are healthy, young and single, with no financial responsibilities, OR are partnered with someone with a higher paying job with benefits) then these careers can be incredibly rewarding.
But, in my opinion, they are not practical careers.
As far as practicality goes-- get into medicine (nursing, etc) or teaching (specifically science, math or special ed). These are all careers that are going to be in high demand in the coming decades. They are not always glamorous, or super-high paying, but it's reliable income with decent benefits and a job market that stays high even during poor economic times (people are always having babies, and those babies need educating and get sick too) With regards to nursing and medicine, one of the most needed fields for the future is geriatrics-- working with old people. As medicine and healthcare progresses, people live longer, and there will be a great need for specialists who can work with the elderly.
