It's all about the process, the journey. The constant improvement and development is what drives people like Elon Musk. They take *some* time to reflect about their achievements, but they always keep their eyes forward. Looking at myself, I'm a completely different guy then ten years ago, but I'm still not 'done' with myself nor do I want to be. Occasionally I force myself to look back at my achievements, because it's too easy to keep looking forward at the things that still have to be accomplished.
