Try as hard as possible

Sometimes we are tempted to not go 100% especially if we are already winning. But that is a mistake. Never underestimate your opponent and never give him unnecessary chances of winning. If we are to draw parallels from chess, there are many lost games that were COMPLETELY won. That's because once you think you won, you start playing less attention and that's exactly when your OPPONENT flips the game and wins. No matter how hard your winning position is, STAY AWARE. This also translates to real life.
