The good old question of what's the meaning of life? 😀
I came up with a saying, after reading a Tony Robbins book, that purpose plus service equals fulfillment.
When we find something that motivates us, which can help others at the same time, we will feel fulfilled.
It's not about money or things.
What motivates you? How can you help someone else? I think when we can answer those two questions, you are on the right path.
