How can we find passion the whole time?

A talk with myself (1) I graduated from faculty of commerce this year. My studying was in Economics for two years. When I was a student I imagined that everything would be easy, I'd find a job that I want after weeks from finishing my exams, I'd complete my studying and start masters this year, but when I finished my exams I found myself searching for a temporary work because I couldn't find the job which I wanted with an acceptable salary so I worked in customer service filed as a call center agent for a well-known company this is my fourth month there, the last month I used to wake up everyday and convince myself to resign and finally I resigned a week ago and I'll leave this job after 25 days. Indeed, I don't know what I'll do after leaving it, but I'm sure that was a good decision I made, because finally I could do what I believe, and what I believe is that I'm not a tree to be in my place, So if I wanted to move, I have to move. It's easy to believe in something but it's too difficult to apply that because you'll lose something to win something else.
