The biggest thing is continuing to become a true GTM engineer - I'm still very early in this process, and I still have a lot to learn w.r.t prospecting, list building, technical SEO, outbound, and more. I think I've been doing a good job so far, but I'm nowhere near an 'expert' at any of these, so I need to continue to learn and grow, and try and fail.
I also want to get better at finishing what I start. This applies mostly to GTM, as my ENG work is more clearly scoped. I've started a few automations that I've not come back to, and I've built out some automations that have not been maintained well and have broken. I want to be better at taking the engineering approach Jack has instilled in me to GTM - maintainability, scalability, and attention to detail.
