Decided to write this before reading any others, so it's fresh off my own mind first.
1. Trees ... first and foremost my favorite part of horticulture.
2. Enjoy interacting and visiting with people.
3. I like problem-solving ... good way to apply it.
4. Working outdoors is awesome.
5. Can set my own schedule for the more part.
Since I started photography too, the trees and people part have definitely helped me in that department too.
