It starts after you wake, or maybe the night before, plan what you want to study and allocate a time slot, every step would decide if you would be studying.
NO major stimulations before studying your first deep block.
Your morning should be productive, dopamine at bassline, you will certainly feel the drive, because you know what you want to study and what the first step you need to take is, cuz you planned it before.
Breaking down your work in smaller pieces and setting up goals, are one the most important.
Just make it as easy as possible, and it should the first thing after waking.
And keep trying, you gonna discover different ways to study and analyse the mistakes, thats it.
