You really don’t need to be optimistic. I’m not. That doesn’t mean that you need to have any problems.
The real issue in your comment is your guilt, and of not feeling like you’re doing enough. My first question would be: are you actually not doing enough? If every person on Earth would behave/live like you, would the problem exist? If the answer is no, then you’re doing enough. Then the question becomes how to get rid of that feeling, but this answer comes first. Because if the answer is yes, then you should be feeling like you do!


It entirely depends on what you want the user experience to be like, and what ecosystem you choose.
So, no idea, give exact specifications.
