If you have an idea, usually someone has already thought of it. If you search on the internet, you can find plenty of ideas that you may have thought of on a general sense. What is not general, is your ideas on how you want to make those ideas come alive.
Being you is the most different thing that is on this planet. Nobody is exactly like you. What you bring to the world is a combination of many things, that can only be found in you. You are a niche within the world. With that, you need to learn to ride your own waves into success.
Everyone has their own path to take, you just have to find the right one that helps you complete your journey. Ride your wave.
