Engineering projects are not all rocket science, but a few are; Engineering designs are not all mathematical, but some are; Engineering teams are not all experts, but many are.
As an engineer, you might create a satellite to measure solar flare radiation headed to earth, or a deep space probe to listen to the stars; or, you might conceive how to help the blind see a sunset, or the deaf hear a symphony.
It may be someone else that develops the optimal trajectory for mankind’s first human trip across the solar system, but it could be you that develops the optimal orthopedic artificial hand making it possible for an amputee to control the trajectory of her own food from hand to mouth across the table.
Either way, you’ll change a life, or the world, or the solar system, or the galaxy, or…
Either way, you’ll make the world a better place.
