title: Awake() and Start()
body: <p>I see that we can initialize Variable in <code>Awake()</code> or <code>Start()</code> and  <code>Awake()</code> will be called before <code>Start()</code>.</p>
  
  <p>When should we initialize in <code>Awake</code> and <code>Start</code> to have the best performance?</p>
