How long have you been on Steemit? And what do you think about it?

Although this is a newcomers community, but I guess that many people here will be older than me when it comes to Steemit

So, I want to know how long have you been on Steemit? What do you think about it (please tell me your honest review)? And has it changed your life in any possible way as some people claim?

I'll be waiting for all of your answers in the replies :)
