I truly believe that we are here to try and make a difference, whether you are religious or not, I think you can understand that concept.  We shouldn't go by things like "Life isn't Fair, get used to it!".  It is true, but I think we owe to ourselves and those around us to try and change that.  We should try and make things as fair as possible so that things have a possibility of getting better.

If we think that things will much better once this life is over, then we forget to enjoy why we are here and what our gift is.  Life is a gift, it can be hard, oh very true, but it can also be beautiful, you just have to start at looking at thing from both sides and seeing it from all angles instead of just one.  Life is much like a gemstone, it doesn't really shine until you get the angles just right, then you see this awesome sparkle that makes it so lovely to look at.  

All of it is a learning experience, from whatever reason or religion or philosophy you subscribe to in that we should take this gift of life and make it work for us and for others, so that as the generations move ahead, they move in a brighter, more peaceful environment.

I don't mean everything is always rosy and we have nothing to worry about, that is just not rational, we have plenty to worry about and problems galore to contend with, it is all in how you approach it and how you decide to deal with each day that makes the difference!
