Hello @preppers,
I feel that you are right about the ideas that you share on Steemit being tangible. Through sharing our experiences and knowledge on this site we can all help each other to better ourselves. What is more tangible than using what you learn to become a better prepper/homesteader/person? Really nothing because the things we do for others far outweigh those things we do for ourselves. Those are the things that can really change the world for the better.
Yes building a worm farm or rabbit hutch has a lasting effect, but teaching others to do those things is even more valuable!
Thanks for sharing this post & good luck in the competition!
