One of the worst things that can happen to us while playing the lottery which also happens in other betting games including stock trading is our EMOTIONS. You will tend to over play and over pay. And that is when your losses surpass your profits.
The best strategy is to choose your numbers the night before to play the next day. Force yourself to get into a habit where you choose your numbers the night before and go about your business. Then just play the numbers before the drawings. For the first drawing play the numbers the night before the drawing. This way you are not tempted to keep playing playing and playing which is very easy to do. And our emotions get in the way when we want to win win win and we think by playing more will get us huge profits.
Get disciplined and easy does it. Increase your profits slowly until you have a huge pot then you keep the same strategy but with larger bets.
