I agree with all the aspects you described but what about people like me who can't sleep at night it's my habit from childhood well it's our family problem we are night owls we sleep round about 3 or 4.am. sometimes i feel so lazy in university but i'm used to it. but lemme try this because i'm fed up from my this bad habit :/ .... somedays i decide to change my routine i actually work on but the next day again the same lame routine :/..
