I don't propose anything. But people can make decisions based on emotion or other factors and I am wondering at what point is that person not an Objectivist? Is an Objectivist only so when they are 100% and is 100% achievable?

What would you propose in the place of reason?

I would say that every important decision should have serious reasons to back it up, in terms of advancing or maintaining one's fundamental values. Most everyday decisions (such as where to go for lunch) are choices between multiple rational alternatives, and don't require a great amount of thought.

And Objectivism doesn't require that every decision lead to a positive outcome. Many decisions involve balancing risk vs. reward, with no guarantee of success. All that a rational person can do is make the best choice given the knowledge available to that person at that time.
