As others have said, Its a way of life. Alot of young lads get into keepering expecting to drive around in a landrover all day doing the odd trap here and there. I've seen more lads jack in after a year or two than i have stick at it.
If your willing to put the effort in and stick at it then u will reap the benefits.
I would advise you to try and get a few weeks or a summer work experience rather than just a week so you get a good look at it rather than a taste.
