I mean, laziness is all in the mind. It's like a mindset that
you have adopted to, due to common practice of it. You must really
sleep and rest alot hence your laziness.
I suggest you get your ass off the couch/bed and go do some
excercise. Or alternatively, you could hang out with a few buddies
and chat. Bond with them and you know, share what's been going on
with each other. You would know your friends more intiminately this
way and build on the friendship. (Unless of course, you don't have
a social circle, not to be prejudiced, but the people i know who
prefers to sleep at home are usually lonely people with no
friends.)
Go get some friends, do some sports, adopt a healthy
lifestyle.
IT'S ALL IN THE MIND
