Trading easiness for guarantee

I remember in school, there were subjective subjects like literature where your grade is based on how someone else, ie the teacher, felt about your work, and there were objective subjects like maths where no matter if the teacher liked you or not, you got your right grade. Try focusing on the part of business that is objective.

What I am saying is that find businesses where the quality of the product is directly correlated with the success of the product. For instance, if you could create an exaflop computer, I don’t care if you are bad at marketing you will be rich. Another example is AI, if you could get software to learn generally, you will be successful. Yet another example, being able to easily control an android(human size) remotely[this could be used in construction, farming, security, elderly care, site seeing etc.].

These are hard problems to solve, but you are trading easiness of producing a product for a guarantee on success.
