Warren Buffet says to never interrupt the power of compounding. All the most successful people have been compounding at one thing for years; decades. But it’s not only for the sake of material success.
Mastery is something to strive for, because it is how humans self actualize. Robert Greene wrote eloquently about the importance in his book called Mastery. Malcolm Gladwell wrote about the dedication required in Outliers; at least 10,000 hours of practice is necessary to achieve mastery. (Both books on my Books for Success list.)
And that explains the costs of switching what you do with your life. Starting over makes it difficult to do the necessary repetitions to achieve mastery. And not achieving mastery is a waste of potential.
I wasn’t taught the importance of this concept when I was young. In fact, I was taught switching and starting new careers throughout life was perfectly fine.
I’d not make the same mistake raising children of my own.
