Guys, I've been in the GTME space this last year only, after 10+ years as a marketer. One thing I can definitely tell you is that the technical aspect of the job is probably the easiest part. If you are already drawn to that kind of work, you should be fine with online information/tutorials. Where I see it gets harder is to be able to be technical and also have business and marketing vision. Being able to do copywriting, work on persona/ICP documents, connect the dots between acquisition channels, branding work and performance work... All that takes year to build. Just do as many projects as you can, read great newsletters/blogs, be curious. My two cents, if that helps :)
