what is a side effect of living with integrity.
a. boosting your self esteem.
b. boosting the self esteem others.
C. boosting your esteem of others.

Answers

Answer: The answer is B, boosting the self self esteem others.

Explanation: When you live with integrity, you influence, inspire and motivate others; not just with your words but with your actions too. Others see the positive example that you are and attempt to emulate you. When you choose to live with integrity you will experience a number of benefits, including:

- You become more valuable both as person and as an achiever. People see your importance and the value you add.

- You get better opportunities. You become seen as somebody who gets things done. People are more willing to trust you and want to include you in bigger projects.

- As the respect and value you command increases, you are better able to pick and choose the projects you wish to work on.

- The positive relationships which you build, lead to more people being willing to work with you. This allows you to get more done.

- You get bigger and better rewards both in terms of personal fulfillment and pay and remuneration.

Boosting the self esteem others is a side effect of living with integrity. Therefore, option (B) is correct.

Why do we need to live a life of integrity?

A person of integrity acts in an ethical manner and does the right thing, even when no one is looking. Integrity in everyday situations can be demonstrated, for example, by telling a cashier that they gave you too much change.

Living our lives with integrity entails always being truthful and allowing our actions to speak for who we are and what we stand for. Integrity is a choice we make, and we must continue to make it throughout our lives.

Integrity brings peace and wholeness to one's life. You can feel at ease in your conscience and be proud of yourself when you look in the mirror. People can rely on a man who is honest.
