Motivation won't just come and pop out one day and make you get your ass in gear. It's YOU who has to find it again.

Don't wait for it to come, go and find it.

Some people are just lazy by nature.

I'm biking everyday now, even though there is snow and ice on the ground, I still go out in below freezing temps to get my workout. Just because you smoke weed doesn't mean you'll be lazy. I smoke nightly and I still manage to get my ass up at 8am and go for a ride.
