1. Life is just like a marathon... only the one who persists to the end can be called the winner.

2. No matter how long the road is, you can walk it step by step. No matter how short the road is, you can't reach it without taking steps.

3. Hard work may not necessarily lead to success; but giving up will definitely result in failure.

4. If a person does not have perseverance in doing things, it will be difficult for him to succeed in anything.

5. The secret of invention lies in constant efforts. ——Newton
