We often overestimate what we can achieve in a short timeframe and underestimate what we can accomplish over a longer period.
One of my regrets is not taking more videos of the web apps I've developed over the years. It's both fun and enlightening to look back and see the evolution of your projects.
I'd advise taking a moment every 6 months or so to record your progress. While the Wayback Machine is a great tool, it doesn't capture the full data and state of a web app at any given moment.
Trust me, your future self will be grateful.
