It’s rather self-centered for me to say this but 24 hours in a day is just not enough to be a well balanced person. It’s either you pick to be academically wise or to excel physically or stay unaffected in your shells. As for me, I have no other alternative but to pick neither.
Merely complaining is not enough. It’s never happening. There are no add-ons to the amount of hours in a day, unlike some value meal or other. Sleep, sm, sleep, you need to dream on..
