Working hard vs. working long.
Working long means clocking in 15 hour days or 80 hour weeks.
Working long means clocking in and clocking out — one way or another your aware of the amount of time you’re spending on a given project/job.
Working hard means doing something very difficult. It means trying something that, if you’re lucky, will have a positive result. There is an inherent risk involved.
You can fail at working hard, you just have to show up if you’re working long.
The two aren’t exactly mutually exclusive, and working long might end up resulting in working hard (if you show up and work efficiently, you’ll likely end up in the position of attempting hard work).
Working hard takes a leap of faith. No matter how hard you try, working long won’t reap the same benefits.
