Your Comfort Zone Is Your Danger Zone
Human beings grow most tired while standing still.
Your comfort zone is the most dangerous place to be, and will drain the life force out of you if you stay there for too long.
You as a soul need difficulties in order to grow. It may seem contradictory, but challenges are what makes life interesting and overcoming them is what makes life meaningful.
If you lack energy when you get up in the morning, find something that inspire you outside of your comfort zone, and go out and challenge yourself.
