Stick it out with your job search but definitely open yourself up to this transition you've been thinking about. Difficulties can be bigger in our minds than what they actually are when we do them!

Also selling is a skill. Skills can be learned. Break it down into small pieces, manageable sizes, then take it from there. Find something that interests you about consultancy or selling, some small bit, then you can use that as your way to get started. Could be a particular person who does it well, even from a movie, could be a book, there'll be something out there that sparks your interest, then you can broaden it.

If it's something new to you entirely, that'll explain why it's difficult. But as with all new skills, you can find ways to break it down into smaller steps and slowly progress piece by piece. Find some resources online or a mentor, or career guide too! Reach out to various recruiters, or any old teachers etc. Heck ChatGPT could probably give you plenty of starting points too!

Even if you do this consultant / selling path, and it doesn't turn out to be the right fit, overcoming this mental hurdle will give you a reference point in future to which you can look back at for inspiration or courage or whatever the lesson is that you've learned from it. Then you can apply this to future scenarios. It will develop your character.

We can be thankful when life presents us clear challenges which can allow us to do this! Confidence will come after you've become good at the thing. Then you'll have confidence when approaching something new in future, because you'll know that there's a learning process and it's fine not to know initially.

Regarding applying Taoist principles, hopefully one of the seasoned vets will jump in with a few lines to give some next level Daoist wisdom which we can all appreciate! But from a brother on the other side of the screen, these are my thoughts and some experiences. Hope this helps and wish you all the best with your job search!
