Quotes from Irving Chernev

Every Chess master was once a beginner

The sign of a great Master is his ability to win a won game quickly and painlessly

If once a man delays castling and his king remains in the center, files will open up against him, bishops sweep the board, rooks will dominate the seventh rank, and pawns turn into queens.

Chess, like love, is infectious at any age - Salo Flohr

Do not grab pawns at the expense of development or position.
