"What will others think?"
Well they will always think what they like whether you know it or not. Know what counts for you. Everybody has an opinion, but everybody shouldn't matter. Remember, when you succeed, those who said you couldn't, will be the first ones to say they knew you could.
Be sure what you want and why you want it, once resolved set move towards your objective regardless of what other say or think. Wise man always listen others, but makes his own decisions.
