Taste is trained: look at a lot, on purpose

Taste is a library of comparisons built from experience. Build it deliberately:

• Spend 20 minutes a day on sites that are well regarded in your field and on sites that are not, so you learn the difference.
• Keep a swipe file (screenshots with one sentence each: what is working, what you would steal).
• Write the why in plain words: "the spacing rhythm", "the type scale", "the restraint". If you cannot say why, you have not seen it yet.
• Rebuild one piece you admire from scratch, at the pixel level, to learn what it is made of.

Within a few months you will notice the small things before you can name them. That is taste forming.
