This is a very common question which people ask ie. scope of a career. Scope is a very subjective term when you use it with career and definition of scope usually changes at different age bracket. A 21 year old might define scope of a career as salary package, whereas 30 year old might define it as job security and a 40 year old might define it as happiness.
As career counsellors we believe that if your aptitude, interest and personality matches a career, then scope, money and success automatically follows.
