Just go through the WordPress or Blogger free blog directories and look at the endless number of sites that people make, only to fall away after sometimes just a single post. I have a few floating around that I don't update anymore but want to just leave them as little time capsules from a past life.
After creating blogs in the past, the reason I stopped writing was because quite frankly, I couldn't be bothered anymore. Writing proper content that you are proud of putting your name to is time consuming and if you aren't 100% committed, any lapse in motivation can spell the blog's demise.
I want to echo the advice that you HAVE TO write something that you are passionate about and keep your posts at a manageable length. You are going to get bored, so don't over commit. I like to mix up the length of my posts so there is a constant stream of 500 or so word posts that wont take me as long, but then the weekly 2000+ word long form that I am really proud of.
Enjoy :)
Yeah absolutely!!! Thank you so much for the advice @forexbrokr :) Definitely an interesting point re: mixing up the post lengths and trying to make just one great long one a week :) Hope you have a great day!
