Discover Yourself!

1......... Have you ever thought what makes a personality? A personality is someone who has a very strong character and is different from other people because he/she has character traits that make him/her interesting and enjoyable to be with. This is the one who has discovered the road to himself/herself and turned all challenges into the right steps in life. We all are just common people. But everybody of us can succeed in his/her life. We can do our best to become personalities. Our life is ruled by three basic choices: what moral values to have, what people to be with and what aims to achieve.

2..........First of all, we have to think about our inner world. People say. "When a man begins to understand himself, he begins to live." In my opinion, it's good to be easygoing, fun-loving, well-wishing and reliable. I can say that I'm a sociable person because I can easily communicate with others. That's why I'm always surrounded with friends Furthermore, I'm responsible because I know all my duties I'm in charge of and I try to fulfill them. So, both my parents and my friends can rely on me. I'm helpful when my friends face either difficulties or hardships. Finally, I'm ambitious because I want to be successful in life.

3. However, I have character traits I would like to get rid of. I think that my serious fault is being too moody at times when I feel unhappy and impatient without a reason. What is more, I often make critical remarks about other people's work or behavior. In addition, I can be obstinate at times. I don't like to change my ideas and opinions even when other people think I'm unreasonable.

All things considered, none of us is perfect. But we have to be optimists in everything we do. I

try to do my best to discover my own personality. I want to change myself and to become better. The person who thinks positively and tries hard to be sensible, honest, kind and caring will be wiser tomorrow than he or she is today.

5. In this year I'll have to make important decisions in my life by myself. My life will be enlarged

with my own responsibilities. I'm sure that I'll make the night steps in my personal growth.

Task 2.1 Read the text and decide if the statements are TRUE or FALSE according to what the text says.

1. A personality is a person who has a character and isn't distinguished from others. 2. Personality is the one who has discovered the road to himself

3. The author is obstinate.

4. Everybody of us must think about inner world.

5. We have to be optimists in everything we do but we needn't do anything to discover own personality. 16. The author hasn't character traits he would like to get rid of.

From paragraph 2 you can learn about

From paragraph 3 you can learn about

From paragraph 4 you can learn about
