What makes an idea worth keeping?

Not every idea survives

Most ideas arrive briefly. They appear, spark something, and then disappear without warning.

Only a few stay long enough to demand attention. I keep wondering what separates those that linger from those that vanish.

Is usefulness enough?

Some ideas are practical. Others are beautiful. A few are both.

But usefulness alone doesn’t seem to explain why certain thoughts keep returning. There are ideas that offer no immediate value, yet refuse to leave.

The pull of curiosity

Sometimes an idea stays simply because it remains unresolved.

Questions have a gravity of their own. They pull attention not by offering answers, but by insisting that something is still missing.

Letting ideas remain open

Maybe an idea doesn’t need to become anything to be worth keeping.

Perhaps its role is only to sit quietly — reminding me that not everything needs closure.

For now, I’m letting this question remain unanswered.
