Then u better dont start.... too evil 害死人 venomous.
For the last few years I had several powerful concepts that I could make few series of apps to create my own businesses, and I know that will eliminate at least 100 competing businesses and thousands of jobs. If I continued I am able to conceive more such ideas. But I did not even want to share with anyone these thoughts and ideas, nor lift a finger to create them. I search google and app store, and know that these things still don't exist yet. The only apps I write now are apps that are my own tools, solved my own needs and fixed my own problems. I showed to people but won't let them have my apps.
