So now, whenever I catch myself thinking vaguely about something really important, like, "It's unlikely I'll forget what I want to say in my TED Talk," I now try to estimate it numerically.
Sejak itu, bila saya sedang memikirkan sesuatu yang penting, seperti -- "Tidak mungkin saya lupa apa yang  akan saya bicarakan di TED Talk." -- Saya berusaha menggunakan persentase.
