I guess that depends on what you mean by success. If nobody ever remembers my successes, if I never make "disrupt" any industry, if I never get to retire, if my works are never immortalized, even if all my software becomes obsolete one day when the SDKs that I'm using no longer exist (which has already happened a few times), as long as I can pay for my family's food by solving problems for other people, I will be satisfied.
