Can you ever be too ambitious

No, you can always be ambitious and more and more. However, the key factor is how you accomplish your ambitions. One can be over ambitious in another's eyes but do all the things in his plans. I don't know how to say this in a structured sense on why it isn't bad to be over ambitious. Basically, a man can be over ambitious in his thoughts and stuff without causing him any trouble. It is the actions that you do that can make you crash and burn on your actions and plans. If you have carefully planned out this overly ambitious plan of yours, then you don't have a problem in your life or your goals. However if you didn't carefully plan out what these ambitious goals you have, then you will have a problem. It all lies with the person, can you self reflect on what you are about to do? Can you self predict or are you willing to think ahead of other people? It's a matter of personal wisdom if you can accomplish these overly ambitious goals of yours.
