There's this thing that programmers say about looking back and being ashamed at the code you wrote years ago and realising how far you come.
If you do this, the latter observation is a good one to make: you probably have come far!!
But also: You should look back on past you with more compassion. Past you did good work with the knowledge and experience that you had at the time.
AND… Don't be scared of, or ashamed at the thought of what future you will say. You're doing good today too!
