Not everyone can write.
Most people feel they can write because they simply did a few essays in school. Writing is an art that cannot be acquired. However, you can always improve your writing by reading more and writing even more. When writing, you put down what your heart, mind and thoughts feel. You should not lose hope because your article did not meet the target that you had planned, you can look for other things that are in line with writing like proofreading, transcription, and many more. Writing is certainly a calling.
