For me, goals and meaning are less an innate property, but things that are built over time as the result of positive feedback from direction and momentum. I didn't start with them, but as I try things, my identity changes to hold a goal more deeply.

An analogy is a rock at the top of the mountain. It doesn't have much direction but maybe vague sense that it could be nice to go somewhere and do something. If it moves around a little, it starts to be pulled in a direction, ever so slightly. The Further it goes, the characteristics of the rock change, pulling it more, and repeating the process.
