explanation: "security" is obtained by "secret-keeping" the "confidentials". if you are "obese", you can get slim through "fitness" but not "growth". if you are "ignorant", you can become knowledgeable by "learning", but not "catching up". 
  if you are "behind", you can "improve" by "working hard". there is no obvious logical relationship between "optimism" and "joke".
