How to get alot time in my day? I've many goals but I tried but failed to do all my work in a day because I've not enough time to do work.?

You'll get better at multitasking as time goes on, but it's important to keep a schedule. If you have 10 things to do, write those 10 things in 10 time slots on your calendar. Stick to it.

do less stuff, noone has time to do everything
