I am in my early 30s as well; and I really aspire to become one of the most influential
entrepreneur. However, my advice for you is to take one step at a time. There are lots of universities and scholars program that offers Science and Engineering courses that will aid your dream of becoming who you want to become in life. However, in my honest opinion, I'd suggest you follow your heart. Go with that course you love so much.
I realize that one of the most easiest way of becoming a successful person in life is to follow your passion. Study a
course you have natural passion for. With that, the sky will be your starting point.
Just my one cent.
