I've started using Marketo a few months ago, my training has been pretty intense and I feel that at the moment I have a good understanding of all Marketo's basics (email marketing, smart lists, smart campaigns and their logic, engagement programs and so on).
I'd like to move towards a level of Marketo Certified Expert (I'm sure it's a long way), but I'm not sure what's next.
What skills should I practice on? Which new tools should I learn to use? What tools are most important for the marketplace?
Where is the best place for learning all of these?
Hope the question isn't too general.
