Right now, you might think that you have nothing.
That is rubbish. (before you attack me on that, please read on further)
At no one point is man left with only nothing unless he is dead.
Understand that at any point in your life, be it the top or the lowest of the low, you will always have this one thing that will stay with you. And that is your thought.
What you think, you become.
Simple as that. If you think that you are condemned to a life of misery and poverty then it might very well be the truth for you. But if you think that you are going to get out of that rut no matter what, you eventually will.
So take heed of your thoughts. Monitor them if you will. Just make sure it is doing right by you. That is, you are doing right by you.
