Startup Idea : Message from the future App

Have you ever wished that some decisions in life to be different? This application will offer you advice as are from the future you. How? Based on the test from the application Message from the future it will retain your behavior in certain situations and can predict the outcome of the decision. This idea popped to mind because I wanted to help my sister who was going through a depression period. I knew at what would lead to, but, maybe, I did not know how to communicate with her. I think that a change in the behavior is more easy to appear when it comes from yourself and that is what I want to realize with this app.
