I watch the video of harun bhai namely save your energy it's a very crucial topic and I learn so many things from it here is the summary
Your main asset is resources time and energy
You have to be out of your comfort zone and give your mind some tasks and thoughts with with which is not comfortable this is the basic and most important part of mental growth
Action pack is you have to divide your work into three parts
One is high energy tasks
Second is moderate energy task
Third is low energy tasks
Do high energy tasks when your mind is most active in the day and when you feel lazy and about to rest you can do low energy task this helps you maintain productivity and utilise your day more and more and more better.
Also there is a point no one can waste your time except you as for example if someone made you wait for him why did you wait emptyly you can listen to the course or put hand free and can do a lot of tasks like you can listen to books podcast that really help you in your mind re wiring and growth
reminders for this
Small decisions consume your mental energy
Take advantage of your time as much as you can
Over thinking destroys your mental energy
No one can waste your time except you
