There is nothing wrong with being changeable or unsure.
As long as what you decide to do, you try to do with all your might or are still trying to do.
It is okay to decide to become a teacher when you are unsure of what else to do, and once you have legally become one, never teach in a formal classroom again.
It is okay to decide you want to do publishing instead, then once you have done it for a year, decide you want to work in a foreign country.
It is okay to not want to work in a foreign country forever, come back, and not know whether you want to do publishing again or teaching or maybe become a writer or a sommelier.
People will tell you that you are wavering, that you cannot stick to one thing, that you are fickle and flirtatious with your future. That you cannot decide to do just one thing and can not make up your mind.
But really, you have made up your mind many times.
You have become a teacher.
You have worked in publishing.
You are studying a foreign language and planning a trip.
You are debating writing when you get back, or maybe viticulture.
In reality, you have made more decisions than they have, and as long as you stick to them, you are not fickle or unsteady
you are just living.
