If you believe you have everything you need then all that you need will come to you.
If you concentrate on what don't want then you will get more of what you don't want.
Instead try concentrating on what you do have, be grateful for those things.
The more gratitude you express in a positive way the more positive will come to you.
It's all a matter of like attracts like.
What you put out will come back to you so concentrate on sending out positive thoughts and do positive actions to attract positive things your way.
