Saúl “Canelo” Álvarez, the Mexican boxing superstar, was asked if he ever gets tired.

“Of course I get tired,” he said. “I just don’t complain. That is discipline. If I have 50% today, then that 50% is my 100.”

What he’s naming is the plain discipline of meeting the day as it arrives, just showing up with what you have available that day. You give today’s strength, not yesterday’s, not the imaginary version you wish you had.

Like the Bhagavad Gita teaches: to do the best you can, to work steadily, without complaint, without dependence on moods, and without worshipping results.
