Well you start with a huge advantage as a UK player as you have access to all sites and don't pay tax on winnings.

If you really just need pocket money (ie you live at home with parents) then you can go 'pro' at any stakes you wish I guess. Pro at $50 sounds like a hard grind, but I guess you will move up in due course right?

There is only one stat that really matters here and that's $/hr. If you are making a sum you are happy with and enjoying the game, then I guess it's fine.

I don't see online poker going anywhere soon (outside US it's still growing strong)and as a non-american you can just stay with the fish and avoid the US sites.

I would investigate playing at Codepoker (Prima site) if I were you as they pay you 50% of your monthly winnings as bonus (to a max of $3000). If you are making $70/day at the $50 tables by way of winnings for 25 days of the month, that would make your monthly winnings $1750 and they would give you another 875 - bringing you up to about $2600/£1350 tax free per month, more than say a trainee lawyer gets paid, nevermind something socially useful like a junior nurse.
