This may sound almost over simplistic and stupid, but I know how to improve things. Life, products, services or any other thing.
To improve things or life you need to remove negative things and add positive things. Don’t just add stuff, you need to remove stuff also. If something is broken, fix it. When you fix things the world becomes a better place.
just look around you, what is positive and what is negative. Toss the negative and add some positive.
