Have you ever noticed that it's easier to recall bad experiences than good ones? This isn't a flaw—it's a feature of your brain. Neuroscience reveals that our brains are wired with a negativity bias, meaning negative events are processed more deeply and remembered more vividly than positive ones.

"Negative experiences don’t just stick… They get priority processing. They’re encoded more deeply. They stay closer to the surface."

This bias was evolutionarily advantageous: it helped our ancestors detect threats and survive. But in modern environments—like social media—it can make us feel more anxious or dissatisfied because our brains are constantly scanning for what's wrong.

The key takeaway? Your attention is not neutral. If you don't intentionally focus on positive moments, your brain won't do it for you. To counteract this bias, actively revisit good experiences: name them, savor them, and reinforce them in your memory.

Remember: what you recall shapes what your brain prioritizes. Make a habit of bringing the good back into focus.
