If you are feeling a bummer. Like having trouble doing something and you are not doing it?
If the issue is that you need to get more energy, then, the thing is that you need to get more energy.
Consider your death bed. People wish they lived for themselves and pursued their passion.
Wake up early, before sunrise.
Drink water.
Do work. Like whatever drudgery you need to finish. Make small progress on it.
Do the dishes.
Do the laundry.
Throw out trash.
Get some wins.
Read.
Go running, outside. Around sunrise.
Lift weights and shower.
Shower.
