Is there something in your life that annoys you? People are lazy, if you have any solution that makes life easier, it would sell.
My dog needs pumpkin in his meal everyday for his digestion issue. I was so tired of opening canned pumpkin, move into a container, put into the fridge, scooping it out, back to fridge, and wash the spoon, every single meal. So I created a freeze dried pumpkin for dog called Happy Olly, so no need to refrigerate, easy to use. It helps me with my life and many other people with similar problem.
I like the short book "Go Giver". It taught me it's all about the value you provide. Good short read
