I think if you exercise your state of mind - my state of mind - is usually more at ease ready for more mental challenges. Once I get the physical stuff out of the way it always seems like I have more calmness and better self-esteem.
I was gone so much in my first marriage. I love the moments when I engage with my youngest daughter now. It's not my thing to sit on the ground and play tea party but I'll do it because it's a moment that will stick with me forever.
