When you are on a roll and feeling confident, it can cause you to go on "tilt". Being on tilt is when your emotions cause you to play differently than you normally would, and does not only happen when you loose a large pot. Many beginners don't realise this and are not aware they are on tilt after winning many pots in a row.

You should not keep on playing every hand just because you are on a streak. You need to control your emotions and play the cards and continue adapting to the table.

However, it may sometimes be correct to play more hands when you are on a streak becuase of your table image. Other players may become irritated at you winning streak, so may become more determined to "take you down" by winning a pot thus calling when they should fold. Basically, you need to see how your winning streak effects how other players perceive your poker style, and adapt accordingly.
