I also really like your point about little beginnings leading to greater things. I have found that the more deliberate approach of using my blog for more, rather than social media, has led to more connections. Reminds me of Amy Burvall’s point about ‘gathering dust for stars.’
It takes a while to develop a system for organizing posts, but it’s really worth doing from the start, or right now. I assure you, if you keep blogging, having a system for organizing your past ideas will help you as you pile on many posts– I rely more on tags and categories to find things than search.
