Try not lose the fantasy aspect in pursuit of realism.
Sometimes realism sucks...
For example:
*Getting sick unexpectedly and dying. Knock on wood...
*Falling down when drunk and breaking and arm or spraining an ankle
*Not being awesome or successful
*Living a plain, ordinary, uneventful life.
*Having to wear the same boring clothes every day.
*Not being able to run around in heavy metal armor with the sword of awesomeness and "1 ton shield of Oh no, you can't touch this, bitch."
*Not being able to just pull things out of your ass and chalk it up as magic.
It's kind of nice how in fantasy fiction, some allowances are made so that life is a little more awesomer. You can sit there and read or play it and be all like, "Dude, wouldn't that be cool? I totally wish life was like that. I'de give my left nut to be Randolph the dual clay wielding midget from hell and part time baker" instead of being all like, "Bummer. I am like sooo greatful for my quasi-meaningful life as an envelope licker and public assistance recipient."
