Perhaps the most important personal trait to have is the aptitude to do the work. In any profession, you must have the aptitude to understand the material. Some people have the aptitude to be musicians, to be artists, to be doctors, to be lawyers and to be consultants. You should truly evaluate yourself and you should avoid the profession if you simply do not have the aptitude.
You should trust the input of the people who are closest to you. Everyone cannot have the aptitude that is necessary for every profession. It is not an admission of inferiority if you don't have it for this profession. If you don't, then work to find a profession where you do fit.
