Simple yet effective. I like the TLC concept and I think it is foundational for any good journaling.
I have been trying and failing numerous times when I wanted to start journaling my day. I think adding to your point, a good idea would be to start as follows since this is starting to work for me :)
- Just jot down whatever comes to your mind with respect to TLC. Do not perfect or fake it.
- Use pictorial words or diagrams if you are too lazy to write.
- Find a specific time of the day to journal and limit the time. This will build the needed habit.
