If you're constantly getting better at what you do then you'll always look back at your old work with a unique perspective. To some, that might take the form of embarrassment, humiliation, etc. But put in a more positive light, you can look at your work and know how far you've come.

I think we should all behave more like the later; appreciate your growth mindset, and remember 5 years from know whatever you're doing now might be unrecognizable.
