A couple types of hard work to highlight along with the associated apprehensions…
The hard work where you know what needs to happen in order to get to the destination and you just don’t know if you want to sign up for that ride. Running a marathon, rebuilding a car, becoming a doctor, going on another world tour. Hard work. Still lots of variables. But there’s a path. You know if you push through and do the hard work you’re going to get there. So the question is simply, are you going to do it or not?
Then there’s the hard work of deciding to do the hard work with no clear path to the result. Knowing you’re going to have to put in a tremendous amount of time and effort in order to figure out if it worked. Cooking Thanksgiving dinner for the first time, starting a bakery, launching an app, building a band. Are you willing to do the hard work even if it doesn’t work out? And if it doesn’t work out are you still glad you did the work?
