"Life is a game of inches"
Is your life a game of inches? What about a game of heart beats or breathless moments? Life shouldn’t be all about hard work, or crap work, which is something only you can define. If you’re working that hard, so hard that you forget to look up while life is happening all around you, then you’re not doing the right work.
Kill the learning curve. Push yourself. Spend your limited time on this earth doing something that enthralls you. Don’t blame your kids for your limits, or your wife, or your parents, or your environment, or God, or anyone. If your life is unpredictable then at least make it about unpredictable moments of self-determination.
