Five years ago, while I started to write first blogs I didn't event think that sometimes it could become some kind of profession. First year I was doing it like a hobby, telling my readers about travelling. I've never been thinking of promotion and of course I couldn't have imagine I will be payed for this in future.
Step by step it became more than a hobby and about two years ago I've started earning money for this. And eventually I realised that I don't need to stay in this stupid office, doing some stupid job just because my boss needs it. Since now I can do anything I want - travel, take cool photos, tell people about my feelings and share some helpful info. And even get payed for this. Incredible!
Later my blog brought new people to my life. It's amazing, I could have never met this people without my blog. Now we can travel together.
Most of "bloggers" are there just about money. But first of all it is the way to speak with people. So if you have your own blog or you only going to start, I'd recommend to. That is one of the best experiences of my life.
