How to move nagative think to positive ?

Hi all
Just got back from Dallas of Texas. What a amazing experience be able to working with the Author of " Secrets to Creating Wealth"by Mr Stephen Pierce. He and his wife Alicia Pierce are Wonderful couple.
As my mentor,they are the inspiration for me to work on my project and e-book etc. So as the result now i like to ask your guys about those question as began to think of how we over come this 7 Obstacle we facing in our day to day live:

1.How do you over come in correct thinking when you facing challenge?
2.How do you over come when you feeling down there are no support system?
3.How do you over come feeling lack of happiness, peace within yourself?
4.How do you over come feeling lack of motivation to learn?
5.How do you over come bad mentor habits?
6.How do you over come feeling stuck in the past?
7.How do you over come feeling you been stuck in the bad environment?

Ok guys give me some your opinion or your little story, i am happy to getting know you for real.
