Sudoku lessons
Why bother so much about not making a mistake - like KS. The point of this life is to make as many as possible. The way of saying “what’s the point of playing Sudoku if you don’t even bother getting it right or wrong” - is actually not the essence of life. The point of life is to make as many mistakes as possible - and get the most out of it.
Now thinking back at your records: would you rather be playing 60 minutes of Sudoku (yes, very stupid) or making so much mistakes at the beginning - then now you can play Sudoku WITHOUT mistakes at less than 5 mins (easy level).
Apply that to your business ideas. Make as many mistakes - live as many.
It’ll be uncomfortable at first - but you’ll find that making mistakes is fine… it’ll be okay and it’ll get easier.
