Call me crazy, call me the Rain Man with this repetitive talk.  But you know what, it freaking works. 

Haphazard sucks and willpower and devotion to flat betting is like seeing how far a knife can stick into you without passing out.  The list truly goes on. 

Wager 1:  $100 wager and win.  $200 in front of you.
Wager 2:  $300 wager and win.  $600 in front of you. ($200 back in buy-in, $200 next wager/$200 side)

If you did lose at this point, you only invested the 2 units of your buy-in, say you bought-in with $1,000 and got your 10 black chips.  If you won at this point you have a $400 win.  Think about it---you are going to wager anyway, why not have a plan and a way to capitalize if it does go your way, instead of just throwing your chips into your buy-in and keep trying for more and more??? 

Here comes the best part, if you won--you are on the casino's money (yes it is yours but you want to gamble like me and you want to win something more than a couple hundred, or if you are in a larger gaming jurisdiction--say Vegas, AC, Connecticut or Florida you can make that $100/1 Unit, $500, etc.)  To me, at this point it is Money Management to a point because you are certainly managing and maximizing your bank roll and chances. Wagers 3 and 4 are the best, '2 free chances' now that you paid your dues on the first two, no further risk on the these two.

Wager 3:  $200 wager and win.  $400 in front of you.  (You now have $600 win and you have nothing
                                                                                 from your original buy-in at risk)
Wager 4:  $600 wager and win.  $1,200 in front of you.  (If you lost, oh well, back to the one unit, even
                                                                                    you won, back to one unit, the same or higher)

Now, if I won Wager 3, I would take at least one more unit from my buy-in, and in this case, that would have been $100.  I would also wager my 4 parlay 'side wager'.  Yes, on top of my 1-3-2-6 wagering bet of course.  With the 4 time parlay, I would set that aside and probably not wager it consecutively, just here and there.  Wager the first time and parlay 4 times.  So with this, I attempt the $100, $200, $400, $800, $1,600 wagers.  If I am successful on that, the ultimate before pocketing, would be $3,200 for a $3,100 profit. 

And, like I mentioned--I don't wager this '1 and 4 parlay' every hand, but it is my separate wager of sorts whether combined with another one or by itself. 

That way, I have extra action-motivation and things going on.  For myself, it works out a heck of a lot better than haphazardly wagering.  Thus, giving yourself real purpose and direction in wagering goals and a plan of sorts.

PS:  You do not have to wager every hand either.  Do not forget: The 1 + 4 Side Parlay is a separate action wager going on aside from your main wagering action.
