I share your addiction of plants. I prefer the term passions over additions. I think part of the problem here is that we have bred a modern society that has developed this expectation of happiness. If you look at levels of contentment around the planet you can't help but notice that poor people in developing countries often seem the most at peace. This peace seems to come from having no expectations or guarantees about future happiness, but rather an appreciation for each day that they are healthy and have food in their bellies. I don't think our modern society will ever be satiated due to the expectations that we have developed as cultural norms. I think addictions come from a too easy life where there is no longer any real tangible risks or challenges. If you take away the challenges and make life too easy maybe 1 in a 1000 will develop positive addictions like a love of plants. The other 999 will fall into obesity. consumption and negative addictions. This is simply the nature of any random population of humans. America has had such wealth that it was a possibility that a large percentage of the population could have followed creative, intelligent, non parasitic lifestyles. They didn't. Neither will the Chinese or the Europeans or the Africans. We are talking about human nature and the fact that the vast majority of humans when given an easy life will simply default to an easy parasitic position. Sorry but the only solution I see here to increase positive happiness is for us to become collectively much poorer until we are stripped of any expectations of happiness
