Putting a paywall on my web without having a product (just yet)

So about 6 days ago I made a waitlist for my app read-what-matters.com . I've also made a post about in the r/SideProject that got over 14k views. Now I have 33 users on the waitlist waiting for my product to be built.

Yesterday I had a chat with a guy who I liked on Linkedin and who is also building apps. I DM him and asked him for opinion about my app. He instantly told me "put a paywall and you'll learn the most that way" so now I'm doing just that.

This really gave me a thought in my mind that I should just ship fast and do not wait for the perfect moment to ship you app. I really wanted to perfect my app but now I just want to say f**k it and just ship. Solve problems when they occur it will put you under a pressure to solve the problems right away...
