The Capture Habit in Your Life

Tell me about the capture habit in your life. A time where you had an epiphany and wrote it down, a time where capturing something that you thought, oh, i'll just remember it forever. 60 years from now, no problem. Were 60 days in the future you had totally forgotten about it, went through your second brain ad said, wow, thank you. I captured this, and now i can use it.
