Selina taught herself enough to ship the gymii MVP in two months, but she's "doing a master's in computer science now" because she wants "a stronger technical foundation."

Her path was to throw herself "into the deep end from the very beginning" and figure it out step by step with LLMs as a partner. She frames formal study as a way to deepen a foundation she's already proven she can build on, not a prerequisite for building. The caveat she repeats is to stay "creative and on the spot," to know "what you don't know" so you can "ask the right thing," and never to "blindly copy and paste" what the tools give you.
