Section E: Guided Writing (5 Marks)

Write a paragraph of 200 words on:

"Success is measured by achievements, not happiness. Do you agree?"

Your paragraph must include:

• Two compound sentences
• Three complex sentences
• A variety of conjunctions

Success is often connected with achievements, but true success should also include happiness. Many people believe that success depends only on money, awards, and professional growth. However, achievements alone cannot provide complete satisfaction because happiness is essential for a balanced life. Although goals and achievements motivate people, emotional peace and personal relationships are equally important. When individuals enjoy their journey, they become more confident and positive. A person can achieve great success, yet feel incomplete if happiness is missing. Success should include both achievements and happiness because life is not only about reaching goals. People should work hard, and they should also appreciate the moments they experience. Since everyone has different dreams, the meaning of success may be different for each person. In my opinion, achievements are valuable because they encourage improvement, but happiness gives life a deeper purpose. When people achieve their ambitions while remaining happy, they experience true success.
