They say 10,000 hours of practice makes you an expert at something.
I believe that statement.
But you also must be very passionate about something to devote 10,000 hours of practice and patience.
Often, what you are an expert at, is also what you are most passionate about.
Passions are life-long. Hobbies are short flings. If you are truly passionate about something, you will eventually reach that 10,000-hour threshold.
So become passionate. Become an expert. Do what you love and be good at what you love.
