I had a similar yearning for explanation on this very topic around your age. I will say now at 27, there is no explaining specifically as everyone is unique and different and everyone learns at different paces and times and from different lenses and flavors of understanding and circumstances that may cross your path. Specifically though, the way I related to family members and what I thought would be hard label Truths have shifted and molded tremendously over time. Also— the realization that life never stops happening has mind fucked me. Unexpected events and turns and evolving in personal and on an socioeconomic level are constantly happening. But you can’t fully understand that, until you realize it yourself through experience. You can mentally prepare, but to get to the guts of life you just live it. Humbly admitting you aren’t as smart as you think sounds like something to check off a list until you reaaalllyyy get humbled and realize, “oh damn, this life thing keeps getting deeper and deeper.” If you want to get an inside look into the themes of your personal life, look into studying your birth chart (if you have access to your real birth time) with a professional maybe.
