Secondly, being narrow-minded. This is very bad in the eyes of most people. I believe this is required as my experiences tell me that people who doesn't agree in your visions give you a hell of negative comments discouraging you from going after that ambition. They just can't see what you see and it's difficult to make them see what you can especially when you are 20 to 30 years younger than them. You will encounter setbacks and failures. But despite this, you should remain optimistic that there is light at the end of the tunnel.
Third, grab the opportunity that makes sense. Not all opportunities makes sense. Never believe in the saying that opportunity only knocks once in your life because if you are to become a success you should be able to make opportunity knock at your door often. There will be times that you may need to step back to succeed. Still this is opportunity at hand either directly or indirectly.
Being realistic. My previous slogan was "Nothing Is Impossible". But after reading the Adidas slogan, "Impossible Is Nothing", I came to realize that dreams should still be realistic. We must learn to adjust and readjust our dreams to make them highly deliverable. Its not about lowering our standards but its about being smart in choosing the level of ambition at that time.
As Jack Welch would put it: "Willingness to change is a strength, even if it means plunging part of the company into total confusion for a while." Aside from the things I learned, there are lots of other habits that go with ambition that we shall discover along the way. Remember, never treat ambition as the starting point but as a companion that will go along your journey in life.
