One thing about betting, investing, business or whatever is..

Never remember how much you have won or lost at this point.

Even though you have lost 10 games in series in a coin toss game doesn't mean that the probability for you to win the next game is anyhow larger than 50%.

Every bet is a new bet.
It doesn't connect with history.

So, never look back.
Start a new bet as it's your first bet.
