Some trainning centers brain wash us newbies into thinking that we can come "professional" in a matter of weeks,,,the course i went on was utter crap,,,but the sad thing is i spent alot of money to try and make a go of things on my own as a
tiler ...so unfortunately i have no choice but to stick at it and do my best!!....and i will !!!!!
get your setting out right and the right adhesives and good quality tools ..also take pride in your work ...surely you won't go far wrong
