When I'm working I'm very purposeful and everything else gets out of focus. Something I've had to work on together with my wife is how to acknowledge each other in the midst of this and keep the relationship going.
My wife whenever I'd go off to work and I'd be kind of anxious she'll say...
I feel an intense intimacy with those who have this loathing interest in me....
When my work gets crazy I make sure to always have vitamins water and proper food with me. That has helped me to lose 33 pounds.
