Unlike a game like blackjack or poker, the only involvement that a player has is in placing his bet and watching as the dealer spins the ball. There are no "tells" like in poker, or no counting of the cards like in blackjack. You are completely at the mercy of the dealer (or "croupier" as they are called).
The first thing you should do, in order to improve your odds, is to seek out a European roulette wheel. There is one less number, so that odds of you winning are slightly greater. Over a full night of roulette, this will prove to be a big advantage to you, as the house % edge is reduced by a couple of %.
