How people ruin their life?

 Sure! Here are simpler explanations:

1. **Using drugs or alcohol too much:** Some people drink or use drugs too much, which can make them sick, cause problems with friends, and get them into trouble with the police.

2. **Spending too much money:** Sometimes people buy lots of things they don't need and don't save their money. This can make them run out of money and worry a lot about how to pay for things.

3. **Not exercising or eating healthy foods:** When people don't play outside or eat fruits and vegetables, they can get sick more often and not feel very good.

4. **Being friends with mean people:** If someone is friends with people who aren't nice to them or make them feel bad about themselves, it can make them feel sad or upset.

5. **Thinking only bad things:** If someone always thinks about bad things happening or if they think they can't do anything, it can make them feel unhappy and not want to do fun things.

6. **Not trying new things:** If someone doesn't try new things or learn new stuff, they might not find things they really like to do or get really good at something they enjoy.

7. **Being scared to do things:** Sometimes when people are scared to try new things or do things they want to do, they miss out on fun adventures and chances to have fun.

It's important for everyone to make good choices and be happy!
