What do you do to change your luck?

I'm going through one of the worst streaks ever. Ok to be fair, I'm playing a lot of parlays. But it's not outrageous parlays. I'm talking 10 or 20 buck parlays to win 300, 400, 500 or something like that. And I'm usually just playing things like City to win against Chelsea (sure winner) or Bayern to win at Freiburg (sure winner). 10 games or something like that. And I just can't fcking win. I'm losing because of one fkn game over and over and over again. Today Fenerbahce fkd me when they couldn't beat fkn Akhisar. A must win game for them to win the league. And they lose 2-3. It's fkn ridiculous. 

Listen, stop fucking parlaying.  I do them once in a blue moon but it's usually two juicy lines together to barely make even money or slightly less.  

All it takes is one team to have an off day and your bet is cadaverous.

Stick to basic lines, singles, and have a betting dogma.  This are required for long term success because even the most elite bettor have poor streaks.
