For sure. When I was 15, I looked back on my 10-year old self as someone who didn't know anything but now I had learned a lot. When I was 20, I looked back on my 15-year old self as someone who knew nothing but now I was an adult. At 25, I looked at my 20-year old self in the same way. Repeat for the next few steps. I'm now 35, pretty happy with how it is going life- and career-wise and I look back on my 30-year old self as someone who was starting to get it but was still rather young and naive.
Today I feel like a proper adult who does adulty things and has life figured out reasonably well, but no doubt 40-year old me will think my current self was still pretty young and inexperienced.
