No matter how hard you try or pray for something, if it is not yours then it is not yours.
The best you can do is trust that life will lead you to where you should go.
If you are an honest and true person then life will lead you to a future that is better than you ever imagined. Even if you need to suffer for a while - it's lifes way of seeing whether you truly deserve a better future or not.

If you are unscrupulous then life will teach you lessons that you must learn and pass before you can get to the next level in life.
If you don't pass these lessons then you will encounter these bad experiences again and again.

In life - you get what you have earned. And if you get it without earning it, then likely you will lose it.
