When you acquire #knowledge, you spread it. Everything is interconnected, if you change, people around you will start to change too. And because those people change, institutions will change. You become a "catalyst" which means that you're causing change, you're putting huge processes in motion. Some of these processes may go by unnoticed but once you're down this path you'll start to notice a lot of synchronicity. Which is some sort of gentle way of the universe to let you know that you're on the right track. This is the most enforcing way to create something, the universe will react to you. We are all able to use our imagination to literally dream things into materialization. We can do this by putting ideas in other people's head, just like how you're reading this text now. But the best way to do this is by building on your own imagination.
Free yourself of judgments, those judgments will become limitations. Don't become sour by complaining how bad situations in the world are, but build the change you wish to see. Build a life that's worth living and remembering. Influence others positively, be a beacon of love and light. Make sure that whatever you leave behind once you die, is all you could offer.
