Son, I don't really care what you do in life or how you go about doing it so long as I can understand and sympathise with the reasons why you are doing it.
You can't predict what will happen to you, what opportunities will come your way, what will catch your interest. These days you can't predict what the world will look like. So there is no point in planning what you will do.
Likewise you can only have loose plans on how you will get anywhere, because life will undoubtedly mess them up. The military say "no plan survives the first encounter with the enemy".
