ohhh don't worry about consuming my time... I am happy to help... First if you connect to me on discord we can chat easier and I can answer the questions faster... I am davemccoy#2479 on there... If you aren't on discord let me know and I will send you a link.
To answer your question, you can either buy Steem and turn it into SP or you can lease the SP with your account... People do both and it depends as to which suits you the best... I am always happy to answer though, so don't hesistate to keep asking ;)
