Advice is free and because of that, it’s usually cheap and in great abundance. The world is full of people with great ideas on how to improve other’s lives and circumstances.
Your ideas can be some good ones, the problem is that not everybody is in a position to listen to them or act upon them. The only person your advice need effect is yourself.
If we spent as much time listening to our own advice as giving it, we could create that better world we’d like to see. We must work on that one thing we can change: ourselves.
