Sometimes we're faced with a problem which seems insurmountable.
We just don't know where to start.
But if we put the enormity of the problem out of our minds and just make a start, a solution will often emerge.

(Don't be put off by subject – you will soon be hooked and you'll be wanting to share it with your friends and colleagues!)
In these challenging times, a little dogged persistence can go a long way.
And, as you move forward, you may well find that what were once constraints become the keys to the solution (the chess move rules). Necessity can be the mother of invention.

At the time of writing, Simon Anthony, the guy in the video, had 200,000 subscribers to his YouTube channel. I don't think this is solely down to the fact that he's good at Sudoku puzzles. He draws us into the puzzle through humility rather than boasting about his own skill. His comments at the end are not about what he has achieved but are an appreciation of the work of the puzzle setter:
"Mitchell Lee (the puzzle setter) has come up with a work of sublime genius … thank you Mitchell."
