Changes are what guide us through our lives from the very beginning. It is something that happens to us whether we want it or not. I am not entirely sure if the episodes I remember were the most important in my life but I definitely can call them remarkable.

First of all, an event that changed my life was moving to a new place. It was not only related to living in new town and unknown environment but also leaving friends from the old place and starting all over again. The feeling of the anxiety before meeting new people and the fear of a new duties as a first year pupil of an elementary school paralyzed me. Now I know it opened me to new challenges and gave me a lot of self confidence.

The second significant change took place when I graduated from high school and became employed. It began a new period in my life hence I realized how hard it was to earn some money and I also found out that money did not grow on trees. It also has had great influence on me until now.

The last but certainly not least change that happened was when I gave up football for playing drums. I had always dreamed of playing drums but I never thought this dream would come true. It is five years now since I started playing drums and I am very glad and proud of what I have achieved.

To sum up, changes are necessary in our life. This process moulds our personalities.
If it were not for changes we would not be able to develop and gain new experiences
