I'm going to succeed

Most important thing in your life is your attitude. Without attitude you can't achieve anything in your live. First you have to visualize your goal, and put your self in that picture. You must fill that the goal is already achieved, and to live with that feeling.
That's important because, if you live and visualize like the goal is already achieved, you are moving the giant mechanism that  make all the things in that order that will help you achieving your goal as soon as possible.

Most  powerful thing that you may use for your growth and self development is how do you see your self. Your surrounding will tell you one thing and will try to "put you on the ground" make you more realistic. But you must know that your reality is made only by you, no one else. They are talking to you like that, because they don't know better, their reality is like that and they think that they will help you with that advise.
If you need to find the people that you can ask for advise, search it from the people who is having similar attitude, and had succeed.
Yes that is right, don't ask for advise a men that gave up his own dreams, because, he will learn you only how to give up.
Your attitude must be strong and when the bad time is here. Good attitude is easy to keep when everything is going smooth, but when things are bad, than we have to find the strength in our self to wake up and to say to your self: Today is the great day, today only great things will happened to me, today I am one step closer to my goal. That is the right attitude.
I am going to succeed, because we can have more than we've got, and we can become more then we are.
