Sorry to hear about your uncle. Sounds like he was a great man who had a positive effect on those around him.
TheNorwegianGuy hit the nail on the head. "Also, when you start to feeling gratitude for what you have now, you perhaps find it easier to live in the moment and enjoy life the fullest. I know many people in here are so ready to get out of the rat race that they sometimes may be forgetting the present and creating their own little race instead of really take the time to enjoy the journey of life :)"
Very true. Since I discovered this blog in January, my outlook completely changed in life, though my day-to-day circumstances aren't really that much different than my pre-Mustachian days. I still have the same job, the same 'extracirricular' obligations, live in the same city, etc. However, I've changed my focus to realize what's truly important. I've learned to be happy with what I have and put less importance on material things. And while my new goal is to achieve FIRE, I'm starting to understand that it's not a race and I'm not competing against anyone to become financially independent. Instead, becoming FIRE is a secondary 'byproduct,' if you will, to living a simpler, slower, more Stoic life.
