I was able to continue my career as a law enforcement officer and work as an educator at a regional college for several years. The hours of each position did not conflict, and there were no conflicting or ethical issues involved with the positions.
So, this was a great opportunity, to provide experience, when I eventually left law enforcement, to transition full time into college academics.
Or you could look into the process of how support animals are trained to work with people with disabilities and have a career or a side-career in the training of service dogs.
Or you could look into becoming an animal-assisted therapist. https://www.online.colostate.edu/certificates/human-animal-interactions/?utm_source=google&utm_medium=cpc&utm_campaign=3-sahai-210701-cpc-google&gclid=EAIaIQobChMI35P01cy8-AIVQcLCBB2u0AH_EAAYASAAEgLgZ_D_BwE
Suzanne recommends the following next steps:
Being an interior designer and real estate agent may be an example of 2 simultaneous careers.
A few things need to be taken care of, however:
1. There should be no conflict of interest between the organizations you work for. Be mindful of any such clauses in your hiring letter.
2. You have to be extremely good at managing time and priorities. I have seen people jump at dual careers for the money/fame and then struggle with both. Personally, I feel, you should prioritize one above the other.
3. Be transparent about it to your employer, as much as possible. That would prevent any possible surprises if they find out later through other sources!
I'm not clear if you mean having two careers at once or not. My experience is that I was an internal auditor for 5 years, decided to make a career change and went back to school for my MBA, and have been a financial advisor for 20 years now. The audit experience was a good foundation, but I knew that I didn't want to do that for the rest of my life. Being a financial advisor is a better fit for me in terms of the work and the flexibility it provides in my later years.
I did not try to hold down two careers at once. This would certainly be possible if one or both are part-time or you can work one during the day and the other at night or on weekends. But don't forget to account for your health (mental and physical) and other priorities like friends and family. I would think you could manage working two careers pretty full time for a year or two, but not long term.
Of course you can always have more than one career, or switch careers at any point in your life. You are in control of your life. I am about to graduate with a BS in Accounting and I have a notary public certificate and a real estate license. My accounting job will probably be from 9am-5pm kind of job, leaving me with plenty of hours left during the day to do notary public work or real estate. So do what you enjoy the most, or simply try to find a job that you can do both of your passions at the same time. For example, I can try to find a job where I can be an accountant for a real estate firm.
