"Track record" is just a byproduct of motivated/smart people trying hard at life. Also there's no such thing as "increasing track record of successful events". You probably perceive it as such because you only learn what the media/people want you to hear. A lot of successful people kept going and going even when there was no glimmer of hope just because they believed in what they were doing, and one day they had an "overnight success". In extreme cases they never even saw their own success in their lifetime (not that I am a fan of this phenomenon).
