Which career shall i choose? model or doctor? 10 Points!!!?

its unrealistic that you could do modelling and study to be a doctor at the same time, simply because the amount of work you have to do to become a doctor, then the little amount of money You make when modelling. If you have the financial support, then there is no harm in giving them both a go, but i would advise you to give modelling a go first (if you are old enough), and see how it suits you, and then you can carry it on as a side job and study to be a doctor as well, and if you don't like it, that's your decision made for you!
