Is it a good decision to make my career in the animation field?

Hi, It depends on your interest and dedication about any field you like to pursue and if you are sure about these things, then no one can stop you to get success.

Yes, if you are passionate about animation. No, if others tell you to take up animation as a career. So, don't ask this question to anyone. Ask it to your heart. Answer with your heart and mind whether you are passionate. If you get a definite yes, then animation is the best career decision for you.
