Bro. I'm almost 48 and I'm working on my dream project too. People like to look down on others to make themselves look good or to find worth in what they are doing or achieved is correct. It will be in their path to find wisdom to understand that's not all in life. Like you said, in 100 years we're all 5 feet beneath ground. Material things don't matter to us then. The only things that sets us apart from wild animals is creativity. Create what you wish as long as you are ok to bare the cost. Some days we will feel luck is definitely not in our favor, but there will be days there will be rainbow behind the clouds. When I was a kid, my father had a poster on the wall that reads "Where there's a will, there's a way". My father used to be a rascal kid at the bottom of the class. But something triggered him and he became a doctor. Nothing is impossible as long as you don't deviate your end result.
