Have you ever noticed that some people feed on the struggle of others? For example, we learn about blockchain and other things while some people don't. And they would hire us or get work done from us for free and get the work done. It's kind of sad and sometimes angry feeling that you struggle and others easily have it. I wonder why people don't make effort to learn and not ask others always about some things. Image Credit: https://unsplash.com/photos/G4Lsfia_6xQ
