Great question - if I feel like taking leisure time I take it. Easy as that. I justify it by kicking ass and optimizing everything else as best as I can. That is what brings me peace. Knowing I do my best. It's a good balance for me, I naturally found a circle of successful people that do the same(birds of a feather). I don't think one should try to be this way if you are not and I do realize its a bit different. But for me its worked great and truly feel like I'm living a better life every day.
