Everybody is "passionate" about some kind of vice or leisure. But you probably have some useful passions buried in there too. It's a waste of braincells to lament how unfair it is that your only passions (drinking & sleeping) are not very marketable skills.
Drinking is a marketable passion - you could become a beer/wine connoisseur, or something like that.
The worse thing that could happen is to discover - like I did - that your passions are in inverse relation with work. I loose positive feelings about programming and start to stress out pretty much immediately when a project starts to feel like an obligation, which makes me 10x less productive at work than on my hobby projects.
