Seeking Advice from the Experienced.🙏

Hi, Builder !

I love this community and want to launch my first SaaS soon.
But I want to learn from your experience, that what does one has to learn to build such awesome things that you all have built.

I'm currently a Sophomore and have learned and built stuff with React, Express & MongoDB. My question is how to build things so furnished and market-ready product like you guys do.

What advice would you give me on how or what do I need to learn or do to launch that first product ?

Or what advice would you have given to your younger self starting out?

Thanks !
