I'm 27. Looking back, I can see myself incrementally change year over year starting from 11 years old. I think sharing details and context on my various evolutions would be too much to write here. Here's a distilled hit list of things I've learned.
Expect evolutions to happen; they're a good thing --- Change is a healthy development of personhood. We change as we see life differently. Our values and motivations adjust (sometimes deeper and sometimes conversely in different directions).
Evolutions can be scary and unstable; be comfortable being uncomfortable --- It takes time to figure out what life throws at us. You might hit stretches where you feel uncomfortable and weak. Press into those stretches. Learn how to be strong in weakness. Figure out how to engage others in vulnerability. Cultivate places of rest. Acknowledge and engage hardship.
