I know what he means. Whenever I get into a funk I end up lying around doing nothing. When I get high it gives me a boost hapiness wise and I wanna go out and accomplish everything. It makes me want to workout, walk the dog, read a good book, and makes me feel my goals can be accomplished. But as with any substance it's not about depending on it for motivation, it's about learning from it to remember that perception. I'd say weed has taught me to do that, even after I've quit.
