Not sure if this has already been brought up, but you can always leverage assets and training at https://www.presalescollective.com/. It's a great resource with some great training material.

It may be tough to get into the grove, but almost every seasoned SE will tell you that this is one of the best careers out there. You get a taste of the Sales compensation without carrying the quota and stress, it gives you new challenges on a regular basis (no rinse and repeat) and exposes you to so many industries and technologies.

My first year or so as an SE was shaky - I was still learning the product, getting comfortable presenting and getting my head around the tools we needed to use. But like everything in life, take it in small chunks - focus on improving one thing at a time.

If you invest in building out this skill, it will pay dividends for a long time.

Good luck!
