I used plain CSS for more than a decade and felt the benefits of Tailwind within 10 minutes of getting started. What fueled the growth of Tailwind is that it makes web development palpably easier.
Do you remember what made it click for you? What was the hard part of writing plain CSS that tailwind made significantly easier?
What were the benefits that you felt instantly? I still don't feel anything and would prefer plain CSS over Tailwind any day.
