Why not? You could pursue some other option, but giving up is no option! Life is a one time opportunity, find your passion and live for it :)
I guess you aren't interested in becoming a CA, well I thought of doing CS later I found that my line was different. Maybe you should make yourself obvious what you wanna be. Even while doing what you like you get tried but you again raise up because you know you love what your doing. So don't stress your self decide your line and be focused:)
Thr issuse is that my parents have high hope and i dont know how to tell them that I no longer want to become CA. I am working and also doing online MBA. But whenever i try to study for CA I procrastinate a lot. I dont feel any thrill when I try to prepare for CA exam. I am preparing for inter exam and i have failed 2 and i dont feel like preparing at all. I am ashamed and embarassed of my self for being do useless.
