The state of your mind

What's in your mind is what will reflect on the outside if you think success, then you will be successful but if you think defeat then no doubt you are already defeated. I can't do it because no one else has done it, i can't live a christian life in school where there are so much peer pressure....If you have been thinking in those lines, it is time to change your thoughts, change your mind to change your future.All that a man achieves and all that he fails to achieve is the direct results of his own thoughts
