If you keep losing over and over again and you can NOT get a hit no matter what you try, follow these 5 steps:

1-Stop playing.

2-Get a notebook and start writing the numbers that hit your state on a daily basis. 

3-Start predicting numbers on paper only. Use whatever system you are comfortable with.

4-Wait until you get at least 2 hits (on paper).

5-Then and only then should you start playing again with real money.
