Anyone begin an ecology degree in their 30s?

I had no idea what I wanted to do when I was 18. I have a business degree that helped open doors into well paying jobs that I have ended up loathing. I’ve gotten to the point though where I feel like I need to make a decision and have applied to some state schools for their Biology/Ecology program with a plan to minor in GIS/Geography.

I have always had a close connection with nature and feel purpose in preserving our environment. I love learning and have been reading more books and doing online courses in Ecology, Biology and the arctic climate, as well as doing some volunteering with conservation groups. I question why I never got involved with it earlier and when I look back I always loved earth science. I felt immature at that time, and only now feel I am mature enough and motivated.

Has anyone else here began their ecology studies or career later on? Any tips for someone pursuing a science degree a bit later in life?
