Yet, it is worth asking, what makes for a meaning life? What makes the 4000 weeks worth it? For some, they chase wealth, power, career success, get one's name recognized, etc - these are milestones to be achieved. Things to accomplish.
Others will say, such accomplishments are not the purpose, let us accumulate as many meaningful experiences as possible. So do things like travel the world, and so on.
But it is worth reflecting, a few years from now, what really is the difference between a dream you had a few days ago, compared with an experience from, say 10 years ago? The difference is very little. Our memories are fuzzy, and to chase experiences will also likely leave us feeling unfulfilled.
Human relationships are also similarly shallow, even if we seek social connection, the odds of it being reciprocated in the manner we value, or of it lasting when we need it, is low.
So what's my point? The point is, whatever pursuits we undertake with the belief out there that something that I accomplish, accumulate or experience will bring me happiness and fulfillment is a futile endeavor.
Instead, if we can function from a state of feeling content as we live each day, whatever the circumstances, then what we do during the lifespan given to us matters little. However long or short, the inner contentment makes it meaningful.
Sorry for the long response, but wanted to share how I look upon this topic.
