It's never about picking winners, it's always about money management. If you remember that you will find a system that you can live with. Too many people let greed get in the way and that will destroy a bankroll you have worked hard to get. My advise is this...each game is 50/50 no matter what the spread or money line project. What matters is how you manage your bankroll, winners/losers will come and go each day.
drunkguy... you are right on! Glaken... you are correct as well. Fezzik... what happens when your higher risk plays lose, or you hit a losing streak of 5 or 6 in a row? It can destroy a bankroll, cause you to become emotionally unbalanced, leading you to yell or scream at someone who is standing in line somewhere only to walk away confused about why you said what you said to them...and while in a perplexed state of mind that you caused got run over by a truck that was loaded down with books, one of which is intitled ""THE ROLLING BANKROLL...and why it will roll away from you."
Bad Karma is the result of high risk management. Think about that.
