Change...it's good for the soul.
I got a degree in Business Administration. The trouble with that type of degree is that it is a broad definition that fits into many specific knowledge's.
I never knew what career I wanted to focus on, so I didn't focus on any of them. I started out as a Retail Store Manager. I then changed to the Printing and Publishing business. Completely new field to be absorbed. After a number of years of that, I bought a Residential Care Home. My wife and I operated it until she decided she didn't like it anymore and I spent the next 14 years operating it. Administering medications, counseling, cleaning, cooking, shopping, bookkeeping, plumbing, electrical, landscaping, painting, wallpapering, laundry, you name it. When I closed the business, I went into Accounting for about 5 years. That wasn't much of a stretch because accounting is accounting no matter where you are. Just different numbers and parameters to follow. I didn't care for that much, I found it way too defined, no freedom to change things. Accounting is not for wannabe rebels.

At age 55, I decided that I had enough of management and trained to be a bus driver. I worked as a municipal bus driver for a few years and then when an opportunity to move into management in that field arose, I went for it and got the job. I retired from that occupation. I now still drive occasionally just for something to do when I'm not playing golf.
I never regretted changing around. It caused me to almost start over many times, but I learned a lot of things and became a jack of all trades, but, master of none. I know now that if I had it to do all over again, I wouldn't do anything different than how I did it. I didn't plan it that way, I just let things happen and didn't worry about it. I raised two wonderful daughters and somehow got them through college. I'm not wealthy like I might be if I had stuck with one thing until I became an absolute expert on whatever I choose. But I'm comfortable and happy with how my life has gone.
