Blogging is a little bit like a trip to Bangkok – it can be as dirt cheap or as expensive as you want it to be. That all depends on your style.
If you’re the sort of person who just wants to document your own personal memories, then blogging will be free, easy and you’ll probably get a lot of views from your family and friends. However, if your blogging goal is to build a larger audience and make money, then you’ll need to adopt a completely different strategy.
