I needed to hear this. I was in a similar situation for this anniversary thing and it kinda broke me. I was disappointed when I felt like the stuff I made was underwhelming, especially for such a special time. In the end, I decided to just get my stuff done at a reasonable pace and celebrate the day as it happened. Even if things didn't go the way I intended, I enjoyed being able to show what I had done for the occasion and see what others did for it.
Hope everyone enjoyed the 30th anniversary.
