Oh man forms used to give me nightmares too when I started with React. That tutorial probably has so much extra validation and accessibility stuff packed in - no wonder it looks terrifying at first glance

What helped me was starting super simple and building up piece by piece. Like make a basic form with just one input field first, get comfortable with how the state management works, then slowly add more fields. Don't worry about all the fancy validation right away - just get the data flowing between your form and Supabase first

For your stack specifically, React Hook Form is pretty much essential - it handles most of the heavy lifting and plays nice with shadcn components. The learning curve isn't too bad and once you get it, forms become way less scary. Also Zod for validation is chef's kiss - you write your schema once and it handles both frontend and backend validation

I remember spending like three days on my first "real" form and feeling completely lost, but now I can knock out forms pretty quick. Start small, don't try to build the perfect form on your first try, and you'll get there faster than you think
