10,000 hours

Being a taijiquan expert is more than just talent. You need to put in the work.

An advanced-level practitioner should have at least 10,000 hours of practice behind them.
Dr. K. Anders Ericsson found that this was true of any art; whether taijiquan, dancing or playing the piano.

Do the maths: if you trained taijiquan for 2 hours a day (every single day) for a year, that would mean 730 hours a year.
At that rate, 10,000 hours would take you 13 years of practice.
