مفيش حد حياته وردية، ومفيهاش مشاكل، وماشية بشكل مظبوط على طول الخط. الفرق بس إن في واحد مبسوط بحياته زي ما هي كده – بحلوها ومرّها – وبيسعى وبيجتهد، وبيرضى بالنتايج اللي مجهوده وصله ليها.. وفي واحد تاني معيش نفسه في جحيم الإستريس وتعاسة المقارنات، ومش عارف ينبسط باللي معاه.
الفرق هنا فرق عقلية مش أكتر،، فحاول تبقى الشخص الأول.
