At the time I recorded this I was doing 75 Hard, it really is about becoming mentally tougher. It is hard to get all of all of the pieces of the challenge in daily, which I have failed at and redone the challenge but when you do it right, you get really good at not procrastinating and you get your shit done. It also helps get rid of procrastination, you have to do something do it right away - it makes you mentally stronger and helps you get more done. If you are interested in the 75 Hard here is the link, no it's not some diet or shit like that, it's totally free and meant to make you stronger.
