How to Become a Freelance Writer : How to Handle Rejection as a Freelance Writer

One of the ways I started handling rejection was I started writing pieces I wasn't very intimate with. I was too afraid that If I put my heart into a piece and got rejected, I'd be too disheartened to continue. So, I read some magazines that I thought I could break into, on subjects I thought would be kind of interesting, but nothing spectacular, then did the research and submitted. I waited until I built up a portfolio before I started writing more complicated and personal pieces.

have you taken any courses to become a freelance writer?
