SMBs or marketers wearing all the hats — how do you do it?

Like the title says, I’m curious to hear from this community: what is life like when you’re doing ALL THE THINGS when it comes to building content, campaigns, and landing pages?

A few questions that I’d love to know more about:

1. How foundational would you say your level of marketing knowledge is across all the things you work on in a day? Are you confident in the work you put out?
2. When it comes to building campaigns internally what's the biggest thing holding you back from launching campaigns easily? Time, team size, performance?
3. When it comes to landing page building, are you more: ease-of-use over speed? Speed over beauty? How do you define what makes good performance on a landing page?

Thanks for your time! Looking forward to this conversation.
