Procrastination and laziness are real.
But no one procrastinates on doing what they like and find enjoyable.
That is why no advice works in the long run if what you do is not meaningful and interesting.
So before worrying about procrastinating, think hard about what you are working on.
When you work on the right things, you will never worry about feeling motivated to work. It will happen naturally and you won’t have to worry about procrastination.
There will be nothing where you love all parts of, so to avoid procrastinating, identify those parts and delegate them, as far as you can.
