Three lines is plenty.
Your TikTok handle. What you sell, or what you want to sell. One thing you are stuck on right now.
That last line is the important one. It is how anybody in here knows what to actually help you with, and it is how I know what to build next.
If you are brand new and have not sold anything yet, say that too. Nobody in here started at the top, and the people who admit what they do not know get answers faster than the people who pretend.
