Try to write about topics you have mastered, if you do not understand anything about Ferrari and does not know what a V6 engine then do not write about Ferrari. We all mastered a subject, and there will always be people in Steemit interested in reading something on any subject, write and revise the text, always try to add more information. I do not recommend you to create very long texts, create a balanced amount of text, but it may seem that the person is reading a book. There are still content with video, make dynamic videos that are not too long. Good luck. What subject you master? Tell me in the comments.
