I think your perception of the meaning of life can be shaped by learning
I think that to a large extent, learning is itself the meaning of life. Or, not necessarily learning, but having new experiences which have never been had. I think these new experiences are in a sense stored in our atoms/spirit, and the build up over eternity (so this store currently contains all experiences of our projected past, with the most recent experiences having a larger component.
There is a link to MBTI here: the N types generally prefer learning and new experiences, whereas the S types tend to prefer to stick to the experiences that they already know are good. However, I don't think that this means that Ns inherently get more out of life, rather this is just a reflection of that principle expressed through personality, and S types are picking up lots of data and so naturally lots of new kinds of data will be there too.
I've had times where I've understood this aspect of life better, or at least had more to say on it because it was fresh in my mind, but generally my flights of thought are lost to me after I had them apart from some few key aspects. Whatever I thought previously, I still believe it highly important to make new formations out of the data we are given to process - our spirit evolves more swiftly this way.
It is important, therefore, to make the most of things and to use any opportunity to create and understand, to input and output. Of course, one may be creative in how to do this, and a monk meditating for hours on end in the same position is learning a lot too - they are learning about the complex structure that is the human brain, and the environment itself is too complex to ever truly be comprehensively understood. There are endless possibilities, and the best part is that those possibilities truly are
endless (if not indeed infinite). Of course, our own life is where we are now and hence what our main focus should be on (which I am not implying that we ignore effects on the world by any means, they are equally important and have to be considered).
