will it be worth it you ask ? isnt following your dreams always ?
on the jobs. well right now it doesnt look to good, lots of people are struggling to find jobs straight after completing their ATPL/CPL. some get lucky.
dont think you should worry to much about your current cv. and if/when you start flying start building that lasting network of people that can help you get a job. and get advice from obviously.
further more there are several ways of achieving your dream. integrated ( which is from zero to hero plan ) or modular, where you do it in bits ( I am currently reading towards my own atpl )
how you want to do it, depends on : how much money you wish to wave goodbye to. time frame, ect ect.
piece of advice though. get the class 1 done before you throw loads of money into lessons, gear and books. just so you dont get a nasty surprise after spending the first 10-12k £
