Please check grammar draft of a part of my resume.

45 days in 10 countries. I left to Europe at about 3 years ago. For this travel, I had to make the money. At that time, I was in university and had been studying in my major. I decided to quit university for travel. Many people around me always told me, "Traveling is most important thing. So if you can go traveling alone or with friends, you have to do that. Seriously!!" As they said, I wanted to look around other countries, people and their lives. I had earned the money through some side jobs.
