Two more questions to ponder in addition to the other two.
Why am I here? What am I doing here?
For too many of us, those are two different questions.
Why am I here? What is the purpose of the finite time I'm spending on this plane of existence? Everyone is here for a reason. I'm not convinced it's "a" reason – many people spend too much time trying to ascertain the single solitary best use of their lives. The choices are innumerable, but it's important that you settle on a purpose that suits your self.
What am I doing here? What are you actually doing, in comparison and in contrast to what your mission on this planet is?
When the answers to those two questions are in sync, you find something closer to serenity. The path ahead is more clear; decisions about which path to take are easier.
So: Why are you here? What are you doing here? Are the answers to those questions the same, or do you have some adjustments to make?
