love it when people say stuff like this. I get 8 to 9 hrs of sleep in a day and pull around 2 grams of protien per pound of bodyweight in a day.
Before you start ripping on my workouts maybe you should look at your eating/sleeping/and lifting habits to find out why you cant do it. I go till failure every workout bro trust me I am hitting every muscle group very hard and intense.
So maybe the prob isnt me not hitting it hard enough maybe you just need to work on what you do. After all your 18 instead of sounding so sure of yourself you might just want to actually listen to others and maybe you will learn something.
