I have been in and out of the industry for approx 27 years, this kind of work is as easy or as hard as you want it to be. Its all about staying on top of it, once you have worked hard to get it to a great standard its all about maintenance, althought the work is very repetitive I get a great deal of satisfaction out of it, staying on top of it is the key, once you let it slip this is when it gets difficult. You need to do yourself a schedule and stick to it, listing daily, weekly, quartley tasks.
