Career-useful ideas — for projects, businesses, improvements, problems you're observing — come at unpredictable moments. Most get forgotten within hours. A consistent capture habit (notes app, paper notebook, even text-to-self) ensures they're not lost.
What to capture
Specific business problems you've spotted. Improvement ideas for your team. Career moves to consider. Books, articles, or people to look into. Patterns you're noticing in your industry. Anything that seems interesting in the moment.
How to use the file
Review weekly. Some ideas mature into projects; most don't and that's fine. The discipline of capturing makes the few good ideas you'd otherwise lose worth the small effort.
Five years of consistent idea capture produces substantial professional advantage. The ideas themselves matter less than the habit of noticing them.
