build distribution first. treat this like a product.

simplest - email list.

if there is an area you are interested in, start writing weekly.

post it in 5-10 relevant subreddits. post it in 7-15 relevant facebook groups.

daily.

give yourself 6 months to get to 1000 subscribers.

now when you launch something, you have a warm audience.

protip: to grow email faster, niche down. and try to talk individually to each subscriber like you would a friend.
