Malcolm Gladwell wrote about the 10,000 hour rule in terms of what it takes to be great.
While I have no idea if that number is accurate or not, there is no doubting the type of sacrifices one must make.
Whether it means getting up early to work, staying up late to work, missing social events or whatever, there are sacrifices one must make to achieve that type of greatness.
It’s easy to want to be great but to actually work toward it requires true sacrifice (and even then, there is no guarantee)
Have a great day!
