It's not that tough…

to comprehend.

If you wish a good life…
Love God
Love everything God has made in the way He would wish it to be loved.
As far as possible live at peace with every person and the creation.
Understand that life is very much more than acquisition and focus on the things that matter.
If it won’t make life better for you or others and/or draw them closer to God its probably not worth it.

The hard part comes in the doing.
