Journal sessions are your post-work reflection time. Account to yourself what you got done that day and what needs to be moved to tomorrow. Write the things you learned and experienced.

Lastly, direct your subconscious by writing about things you want to focuson tomorrow.

This end of the workday journal session need not be as long as the morning session. Greg McKeown, author of Essentialism, recommends writing far less than you want to — only a few sentences or paragraphs at most. This will help you avoid burnout.

A primary objective of this session is to mentally turn-off work-mode. Just as in physical training, you need to rest and recover between work days in order to get stronger.

Use this session to completely unplug and detach from work. This is your time to recover and be present with your loved ones — there is more to life than work.

ingrains your learning

when you write down the things you’ve learned, you retain them far better. Even if you never re-read what you’ve written, the simple act of writing something down increases brain development and memory.

Neurologically, when you listen to something, a different part of your brain is engaged than when you write it down. Memory recorded by listening does not discriminate important from non-important information. However,writing creates spatial regions between important and non-important pieces of information — allowing your memory to target and ingrain the important stuff you want to remember.

Furthermore, the act of writing allows your subconscious mind to work out problems in unique ways, intensifying the learning process.
