Hi and welcome to steemit - Enjoy your time and find a community that you are interested in. The best advice I can give you is Just DO You!! You don't have to write 30 paragraphs to get an upvote - for me - unless its a chapter in a novel - that would just make me switch off. Write what you want to write and you will find people that want to read it. The best way to find those people is to make meaningful comments on posts you like and don't forget to upvote them. I've given you a follow to see what you do :)
