Do you believe that positive attitudes determine success ?

No.
Ruthlessness, exploitation and deception determine success.

There’s nothing magical about a positive attitude that makes the universe come around to your way of thinking, but it’s a factor in other drivers of success. In tasks that require social cooperation, people tend to support those with positive attitudes, because (with the possible exception of @ragingloli ~) we naturally want to believe that things will work out well. In individual endeavors, a positive attitude leads to persistence, which is important to success.

No, it helps make any endeavor more enjoyable for you and might help a project be successful but it is not an indicatior or guarantee of success.

No. A positive outlook helps and is valuable in drawing others to you but there is no magical manifestation of anything from a positive attitude alone. If ” The Secret” were true there would be no wars or suffering as everyone would only have to wish for peace and behold, it would be. haha

Not necessarily, but it does help. A negative attitude may cause you to overlook certain opportunities.

Being gung-ho is wonderful but there are a lot of variables that determine success (various things depending on what, specifically, you are referring to being successful with).

It sure helps when raising children. That was the number one thing I wanted to be successful at.

I think it seemingly helps a lot. What really helps is not having a negative one.

I really feel that positive thinking is overrated. Being successful at most things really comes down to sheer determination and motivation. Screw both self-help and the ‘secret’. Positive thinking doesn’t hurt though, but it doesn’t lead to anything beyond that to me.

There’s nothing wrong with a little healthy dose of pessimism too to smack one back down to reality, and to help them become more effective in pursueing their goals.
