How many Steem Dollars Do You need To Live?

Hi,

My name is Mik. This is my first post in Steemit. 

I have no idea how this steemit works, but I see several people posting about living on Steem $$?

So my question to all you steemit users is: How many steem $$$ do you need in a day to live?

I need at least £30 per day here in Ireland. How many Steem$ do I need to target £50?

All replies welcome ;)
