What is the most important thing that you can do now that will effect you even after death?

This is not for christians or any with restricted religious beliefs or conditioning, I should say.What matters the most while we are alive is how much we evolve to the highest possible vibration or frequency while there is breath still in our bodies.We must evolve mentally,spiritually,physically,emotionally as high as we possibly can before we leave our bodies.This only applies to those who believe our spirit never dies.We will pass from one dimension to another when we die.That's why it is imperative that we work on ourselves as much and as hard as we can while we are in these prisons called the human body.We will go to the next level of spiritual evolvement according to the vibration or frequency that matches where we are when we pass from these bodies back to spirit.I for one am starting to realize that more and more everyday.We have to release ourselves from people,things,and addictions,etc that is keeping our vibration on a lower level.I for one don't want to repeat this dimension over again, how about you.I realize this is far out of left field for most that may read this thread.However,this is only for those who get what I am attempting to say using words that have many different meanings.
