I was a lucky cause i was a country boy, boy scout who grew up camping. So I was well aware of the hardships living in the bush before i went. But The demanding level of focus and organization to properly plant that many trees in a short time totally surprised me. My first day I planted 200 trees since I didn't know what to do. It took aver a month before I was fit enough, strong enough and smart enough to break 2000 in a day.
