I told you what I did when my first real transformation from unhealthy to healthy happened in my early 30's . Now I'm 41 and I'm having second transformation beyond what happened in the first. Most people really need the first transformation. And one of the driving factor of getting it rolling reasonably well was that I realized how little was truly required to get a lot healthier. There ways to optimize it, but most important thing is to make one simple change and stick with it. Two were real changes I decided were the lifting weights and slowly reducing number of spoons I put sugar in my tea. Everything else was just what I did naturally anyway. The huge point helping me to stick with it was that there were only two simple rules that I had to stick, and both of those were low enough effort for me to stick with.

It wasn't completely without civilization noise, but it was something where I could actually think better when walking outside than when sitting still in front of computer. It was quiet enough that fresh air and walking actually helped me to think.
