Problematische workout

citaat

Problems are to the mind what exercise is to the muscles, they toughen and make strong.

Norman Vincent Peale

Time is free, but it's priceless. You can't
own it, but you can use it. You can't keep
it, but you can spend it. Once you've lost it
you can never get it back.

Harvey MacKay
