Just got first few paying customers

I left my high paying job 18 months back to work on my own products. For the first 10 months, I just procrastinated by reading books and doing busy work, where I learned NextJS and all the latest frameworks, but never shipped anything. To make some money, I joined a friend's startup as CTO, to help him automate parts of his business, which gave me enough time to learn about building a SaaS business.
In January this year, I started feeling the pressure of doing something about the fact that I had not built anything. So, I bought a stopwatch, and I would everyday start it as soon as I wake up and start working on my first product, which was accuhire.co (dead for now) I built it, but didn't market it at all. I just kept adding features to it, until in march, I got bored and stopped working on it.
I then built 3 more products, which followed similar fate. But I got good at building things fast.
Because by july end, I had built 3 new products. Interviewloop, Funnel and AskSilika.
All 3 didn't get any customers, because I spent zero time marketing them.
I think all 4 products had potential, and others had found success with similar products with better marketing.

In july end, I started working on Frameloop, which is an AI video tool. I started working on it because I had this idea since 2019 and thought now is the right time to work on it.

But, I made a few changes this time on how I was going to do things. I found a friend to work with me on it, where he would help with coding, and I would focus on marketing. Having someone else alongside really helped with staying focused. Now, I couldn't abandon the project, like I had done in the past. Because that would impact my reputation with my friend.
We had daily working sessions, and in one week we had a working prototype. Then I saw there were already many similar tools out there, doing great. That made me feel discouraged for a couple of days, but then I went bounced back.
I thought, the market is big for everyone, and I do have a unique take on the problem. I wanted to make it extremely easy for anyone to use, and actually make videos that are worth watching.
My take was that I should give users a really good first draft which is publishable, and give them tools to easily edit, without writing prompts etc.
At that time, existing tools didn't have that feature, which became a selling point for us.

I then started promoting on reddit, twitter and discord groups and finally found first paying user. It's a small amount, but for some reason it feels bigger than the paychecks I have received in the past.
