• If a plan says to use flat heads, ignore it and use Phillips screws.
  
• If anything comes with flat head screws, throw them away and buy Phillips screws.
• If anyone suggests you should use them, hit him in the head and buy Phillips screws.
• If your best friend buys some for a project, hit him in the head, make him return them and buy Phillips screws.
• If your life period partner brings flat head screws, get a divorce, and buy Phillips screws.

That's all.
