Give Yourself Time to Think. Most people keep themselves much too busy. They confuse activity with accomplishment. If you want to perform well, you need to think well. You can't do that if you never set aside time just for thinking.
Find a Place to be Creative. I believe that a person who possesses mental discipline can think anywhere. However, I also know that some environments are particularly conducive to creative thinking. I really like running along the trail out at a lake nearby where I live. It's usually me, a few birds, maybe a rabbit or two, and the waves of the lake. I even talk out loud to myself. (OK I've startled another hiker every once in awhile). Figure out what works for you.
Force Yourself to Think. If thinking were easy, everyone would be good at it - and everyone would be successful. The truth is that thinking can be hard work. That's why you need to make it a discipline of your life. Give yourself a goal to think for a certain amount of time everyday.
See Problems as Opportunities. People who achieve their dreams don't take no for an answer. They are undeterred by obstacles. And they see problems as opportunities. That, in a nutshell, is the essence of entrepreneurship; seeing opportunities in problems. Learn to think that way and you have unlimited resources for success.
Challenge Assumptions. One of the most insurmountable obstacles to successful thinking is the phrase, "But we've always done it this way." It was Robert Kriegel who said, "Scared cows make the best burgers." You can't buy into the same assumption as everyone else and think differently as successful people do. Don't take anything for granted.
Explore Every Option. Unsuccessful people think there is one right answer to any problem. Successful people understand there are sometimes dozens. The trick is to find as many as possible so you can use the best one for that given moment.
Recruit Other Good Thinkers To Help You. Nobody ever achieved a big dream alone. Successful people know that they are not big enough, smart enough, or strong enough to do everything themselves. They get help. If you want to succeed, work with others.

"A minute of thought is worth more than an hour of talk."
