If you are not passionate about any domain, don't just do it for doing sake. If you are not interested in pursuing engineering, you must find your inner calling and develop some clarity on what are your interests and what are courses around your interests. However, I must mention that only hardwork and your commitment to whatever you choose finally will pay. Stability comes with pursing your chosen path with honesty, integrity, knowledge and hardwork.
