Learn to cook.

Like, seriously, learn how to make something so you can feed yourself. Don't rely on frozen pizzas and instant ramen to get you through (unless you're in college). 

I'm not saying you have to become a Michelin star chef, [If you do become one though, great!] but it's nice to be able to whip up something nice for yourself or a guest every now and then without having to order takeout or spend money at overpriced restaurants.

But just a feeewww words of advice regarding cooking:

1. Don't set your stove on fire (been there, seen that)

2. Don't set your sink on fire (been there, done that)

3. Know how to use kitchen utensils so you won't break them (been there...several times...)

4. If you know your friend can't cook worth a , keep them OUT of the kitchen no matter how much you love them

5. Get a smoke detector

6. Step AWAY from sizzling breakfast sausages. Them little buggers get NASTY. (I still have the burn to prove it)

7. Pray that you'll concoct something relatively edible

Good luck!
