I work as a freelancer and one time I had a client that needed some work done on a crypto website. I was so hyped up because the money was good so I jumped on it. Fast forward 2 weeks later I still couldn’t figure what the shit I was doing as the client kept asking for update.

Yes, I have experience with blockchain but my skill on Javascript just couldn’t help. I did google and also ask questions on S.O. but it wasn’t enough to get me on track.

At the end, I reached out to the client and apologized for not being able to meet up with their request and then recommended someone else.
So I’d say “I lost faith” on my skill as a Javascript dev at that moment for not being able to use some blockchain APIs effectively and also look forward to improving my catalog.
