What is harder for you.. building the course or trying to market it?

I always hear people say just make a course but the deeper I get into this the more I realise there are two completely different battles

1. actually creating the thing

2. convincing anyone to care about it

Building the course feels hard in a sit down and do the work kind of way. But marketing… that feels like another universe. Talking about my work, putting myself out there, posting consistently figuring out what actually resonates it is exhausting in a completely different way.

So I am curious how it was for the people who have actually done it.
Which part felt harder for you?
Was it easier to sit and record lessons, or did marketing wipe you out way more?

Would love to hear the honest side of this.
