few basic tips, drop a level line around the wall aprox 3 tiles to the bottom of the wall and stick to it spread you adhsive evenly, try and work from a full tile in the centre if possible, make sure you work it out correctly so you will not have small cuts, take your time ot: like others said i would try and stick to one trade if i were you learning things like tileing is awesome because the very reasons you said, but in the building trade you have to get the qualifications for a reason, so building regs can be passed and clients are getting exactly what they a paying for not just somone who has done abit of this and that, if it was that easy people wouldnt do years at college or apprentaships ect, like i say its great to know these things but try and get your mind set on one at a time. sound like abit of a twat in that hope you dont take offence mate and hopeive helped abit Paul
