I know your feeling, I'm filling 2nd external 2TB drive now, but I always try to back to older photos. I trying to see if I can do better correction or retouch, or figure out what went wrong back then to not make same mistakes in future. I also have feeling that with modern photography value of single frame is smaller, yet outcome of it is that we can create even better work. Still some of the magic is gone during the process. Nowadays everyone with mobile is photographer and it's even harder to stand out from the crowd. I keep getting lost from time to time, but I believe everyone else trying their steps into photography world have same problems...
Also, your taste in editing can change over time quite a lot. There are 'trend' editing styles I think that aren't as timeless as they first seemed :)
I am hobby only so for me it is just a journey of my life. Sharing them on Steem is fun though and it means in my articles I only use my own photos which hopefully means less copyright issues in the future :)
