I have to write an essay using the assertion "Man is his own worst enemy" I support this statement but I need examples that are tangible and valid what are examples of this ?

Suggestion - look in today's paper. You will see many stories in which a person has made a decision which has brought about serious problem, not only for the person but also for others.

Other suggestions... check the computor news section; look at the "entertainers", "famous" people who have really messed up their lives by making poor decisions. Think of disasterous historic events that were brought about by one person's decisions. Example. Idi Amin
This sounds like a interesting paper to write.

thanks for your suggestions

Its a difficult paper to write

To support the assertion "Man is his own worst enemy" in your essay, you can provide tangible and valid examples from various contexts. Here are a few examples:

1. Self-destructive behavior: One concrete example is when individuals engage in harmful habits such as excessive substance abuse, neglecting their health, or engaging in risky activities that put their well-being at risk. This demonstrates how people can become their own worst enemy by acting in ways that are detrimental to their own physical and mental health.

2. Procrastination and self-sabotage: Another example is the tendency of individuals to procrastinate or engage in self-sabotaging behavior. By continuously delaying important tasks or deliberately undermining their own efforts, people hinder their own progress and success. This self-defeating behavior can lead to missed opportunities and a cycle of frustration and regret.

3. Negative self-talk and low self-esteem: Many people struggle with negative self-talk and have a tendency to criticize themselves excessively. This self-deprecating mindset can erode self-confidence, impair decision-making, and hinder personal growth. By constantly undermining one's own abilities and potential, individuals become their own worst enemies by limiting their own achievements and happiness.

4. Internal conflicts and self-doubt: Internal conflicts and self-doubt can often paralyze individuals, preventing them from taking action towards their goals. When people are plagued by self-doubt, they may hesitate to take risks or make decisions, perpetuating a state of inertia and missed opportunities. This internal struggle and lack of self-belief can undermine personal growth and advancement.

Remember, these examples serve as starting points for your essay. It's essential to expand on each example by providing relevant evidence, reasoning, and personal experiences or observations to strengthen your argument. Additionally, consider exploring counterarguments and addressing them to provide a well-rounded perspective on the topic.
