To me, self-driven is to be your own motivation, to always push yourself forward, to always want to be in a better position, always want to upgrade or try to learn, not looking for public opinions, not looking to be validated by anyone. Your work results is your validation that you need, not scared to take a risk, not scared to go beyond to reach that extra mile in order for you to be different from other people or even to achieve your goals, of course, in a reasonable doubt. Being able to actually go through the risk and go through what you doubt yourself in or even if you're scared of a subject or you think it might not work where you actually just put your foot down and believe in yourself and keep going, not giving up if something doesn't work at first. Always try again and always keep in mind that the goal that you have in your head will actually manifest itself if you're self-driven enough to go get it and achieve something that you need or want.
