It's a good question, and falls in line with the Tetris article. Mistakes stack, accomplishments disappear. Are your decisions, even the smallest ones, working towards accomplishments, or towards making mistakes?
If the answer is mistakes, then you need to start looking at the next falling block (Tetris or Domino), and plan ahead for it. Keep yourself from getting knocked over by the blocks. Adjust how they fall, even minutely, and you can change the course to something more beneficial to you. Enough little changes can net some big results.
The only one who can move the blocks is you.
