This has worked a treat for me so passing it on.
1. Make a list of the 3 things to do tomorrow.
2. Pick a scene from your life of some length that you remember with great detail and with some fondness. Start playing it back in you head, let you mind tell it as linearly or non linearly as it wants.
I have a poker hand where I made an apparently crazy call [Not really, there was massive pupil dilation by an amateur]. It's a good candidate because of length and some vivid moments in the hand with big characters involved.
3. got to 2. If you're conscious of repeating, appreciate your relaxed state.
