How to Become Super Confident?

Nice title i'd say but what does is actually mean to become Self Confident ?
There are many ways in which we can define self confidence but they will fall down to this one:"Believing that you will achieve your goals despite of any obstacles you face".so self confidence is an attitude of ''can do it''
Good,so how can i cultivate and maintain this attitude.
Here are the keys to unlocking your full confidence and achieving all that you want and make no mistake if you take these keys to heart you will fly so high cos these keys have been derived from observing hundreds of successful people.
1.Burning desire .How badly do you want to achieve that goal?this is the single most powerful thing you need to achieve it because our emotions (feelings) rise and fall based on our circumstances so we can't really rely on them to get us to where we want to be but if you are so passionate and have a strong desire to make it happen then despite all the obstacles you face you will find a way to make it happen.
2.Make it Crystal clear. Visualize your goals as much as you can to the simplest detail cos the more it is clear in your mind the more compelling and enthusiastic you will be about it and the more focused you will be achieving them.
3.Devise a plan.Not necessarily a detailed plan or written on paper but road markers to guide you a long the path and it has to be clear in your mind.
4.Do What ever it takes!,you must decide wholeheartedly that you will never give up till you make it happen.
5.Screw it,just do it!.Don't analyze too much just do it and success will follow,remember that birds can fly despite the fact their heavier than the air!it is because they don't think they just FLY!
6. Failure =Experience!,needless to say that every failure you go through only makes you stronger so accept failure as part of the process of success and you shall rise above your failures.
7.Persist,Persist,Persist!, Persistence is about pushing on and keeping the faith that things will turn out well at the end just like the smith who is developing strength by overcoming resistance.
8.Faith it till you make it!.know that Faith is stronger than fear and if you believe you can do it then you have won most of the battle!.
