It all depends on the particular game, One thing I can suggest is if you are ahead in pieces then you should just try going for checkmate instead of trying to capture more material. Another thing, if you see checkmate go for it immediately, you don't want the game to end in stalemate.
How do you prevent draws?

If you are going to take ALL of the opponent's Pawns and pieces, then make sure you don't walk into a stalemate. Draws are only annoying when you are careless.

Stare at the board. Think about every move I make. Make sure it doesn't lead to stalemate or a type of draw.

yes dog lover, it is super annoying when you are clearly on the cusp of victory , only to end in a draw. this happens to me more times that i wish to admit. i am unclear sometimes and walk right into stalemate...

How do you guys prevent draws???? Draws can be really annoying especially when your winning!!
If a draw happens when you are winning either you have blundered or you were not actually winning. If you are on top try to snuff out any potential counterplay for your opponent. No need to be grabbing extra pawns if you already have an extra rook for example. Secure your king by tucking it away or give it luft so there are no back rank mate issues. That sort of stuff.

The only certain way to avoid a draw is to resign before there's a chance of it happening (1. resign is best). If your opponent manages to get into a situation where they could swindle a threefold repetition from you, then show them you don't accept their attempt to draw the game by resigning! Ha! That'll show them who's in charge!
Seriously, though. If your opponent manages to get a draw when you (thought) you were winning, then either you weren't as ahead as you thought you were or you made a major blunder somewhere and allowed it to happen. You have to be more vigilant when you are winning - double check that they don't have any stalemate tricks or can sneak their queen in for a perpetual. They say that the hardest game to win is a won game.

Stare at the board. Think about every move I make. Make sure it doesn't lead to stalemate or a type of draw.
Good! That is what you should ALWAYS do!

Right? Its sooo annoying!
look out for perpetual check chances, try to avoid them.
I remember I sacrificed 3 pieces to create a perpetual checking chance on a game I blundered a queen.

In chess, there are several ways that a game can end in a draw. Make sure you know - and understand! - them all:
- Draw by agreement
- Stalemate
- Threefold repetition
- The fifty-move rule
- Insufficient Mating Material
In addition to this, you might want to study which openings, statistically spoken, are more drawish than others.

#1 answer: If you are in a drawn position then give away material lose. That simple to avoid draws.
#2 answer: If you are one of those strange people who mean you want to win instead of losing (losing builds character!) then my tip is: whenever you promote make sure you don't stalemate, or if their king can't move make sure that their other pieces can't sacrifice themselves.
