Whatever we think but this is life, we may plan not all the results we get in accordance with what we plan.
Like life that can not be separated from 2 basic things, that's how we try to understand will live. Accept or reject, go or come. Though it is sometimes bad for us but always the final result will be decisive.
Yep, there cannot be one plan for life, it keeps changing and evolving. Therefore we all got to be spontaneous.
