Improving Analysis Skills

According to Dan Heisman in his great article Bootstrapping Analysis Skills

The following are what make you a good analyst:

• Will to analyze the position correctly, move after move.
• Patience to analyze the position thoroughly (but keep in mind the
  clock – see “g”).
• Analytical thought process to know what steps to take.
• Board vision to see what is happening (statically) across the entire
  board quickly and accurately.
• Tactical pattern recognition – the ability to quickly and accurately
  recognize and assess basic safety issues.
• Visualization to keep the imagined patterns correctly in the mind’s
  eye when looking ahead.
• Micro time management determines the length of thinking time to
  take before one settles for a “best so far” move, assuming the
  “best” move is not found by then.
• Deductive logic to see which moves are candidates, and what is
  forced and what is not.
• Quiescence recognition to know when to stop analyzing lines and
  evaluate.
• Awareness of danger/criticality assessment, plus the recognition of
  The Seeds of Tactical Destruction.
