What is the difference between confidence and over confidence

Confident When your attitude matches your ability is confidence. Attitude and ability of a person is equally proportional Behaving like a innocent but genius actually. Finding the possibilities in a difficulty. Concentrating the process (90%) and the result (10%) Attitude of a person will not be changed by Successes and failures.  Liking to be an important-invisible-part of team to achieve a goal Doing a lot but speaking less Working hard to buy a bicycle Reading a quote and trying to realize it I hope the above points will help at-least anyone of you. I (Firt-person-sigular "I" - It should be always written in block letters only) Thanks (While composing mail write your thanks in title case like "Thanks").

Over-Confident When your attitude crosses your ability is over confidence. Attitude and ability of a person is inversely proportional Behaving like a genius but innocent actually. Finding the difficulties in a opportunity. Concentrating the process (10%) and the result (90%) Attitude of a person is being sensitive to successes and failures. Liking to be an usual-gimmick-kinda-part of team to achieve a goal  Speaking a lot but doing nothing Buying lottery ticket to own a car Reading a quote and believing it without trying to realize it. I hope the above points will help every-one of you. i (It is showing your careless attitude). THANKS (If you write in block letters it means that it is just for formality).
