For many years i bet on everything and it did not matter what it was, needless to say i lost everything i had 3 times before i was 32.
Im in my mid 50's now and 15 years ago i was fed up with betting on sports. It took me years to figure it out. Listen, most people say it's fun to bet and hey the game is on TV so lets bet it, forget about it, i have learned to treat it as a business and study study study.
There is so much info out on the net if you do a little homework you will increase you winning percentage period.
Only bet what you are good at, if you do well in Baseball bet only Baseball, Football then bet only Football and so on.
When you invest your hard earned money don't you want a return on it ?
Be wise and after you cash in then go and have fun and remember bet only what you are good at.
