I agree 100%, you have to work hard and be motivated if you want to succeed at anything. But I also believe that you cant fully learn a trade in 2 or 4 weeks, but after reading lots of other posts over past weeks a course seems a good stepping stone to becoming a good tiler.
Anyway got myself booked onto the chase tiling course, and hopefully in few months I'll be able to pass on some useful advice to another newbie, like lots of you guys have.
cheers for the advice
