It takes time and effort to document your thoughts.
But it is a worthwhile exercise.
Because it allows you to look back at old times later and realize how things were at a particular moment in life.
If you run a startup then through your once a year blog post or video you can document and show your progress year on year.
A year-end review can help you see how well you followed through on your plans, and what transpired in the year that was.
You do it in the present but it serves you in the future as well. It is like an investment that pays back later.
Do you think it is a worthy use of time?
