Decisions were made for me for most of my life. I knew I was going to college because my parents paid for it and it was what was expected of me. I had planned on being an architect.
While going to school, I worked part-time at Sears selling men's clothing. I was scouted by the owner of a men's clothing boutique and was offered a manager position. Our best customer, who owned a tour company, offered me a position in sales. I really didn't want another sales position but I took it. That led to me being picked up as a local sales rep for a cruise line. I spent my career at a couple of cruise lines and retired as VP of Sales. Neither sales nor travel were decisions I would have made, but the opportunities presented themselves. Of course, I ultimately made the decisions to move forward in each case.
The best decision I made own my own as an adult was moving from South Florida to Dallas in 2006. I'd done some research and Miami was significantly "overvalued" and Dallas was "undervalued". I sold our house and my mother's and bought two less expensive (but nicer) ones in Dallas, allowing me to pay off both at 49 y/o. I also had the benefit of working from home until I retired 14 years later because I managed a group of salespeople located all over the country. Our headquarters was in Miami at the time, then moved to Seattle, so I never had to live near headquarters.
There are many situations life throws at us, both good and bad, and ultimately our decisions come down to how we handle them.
