Everyone is different, but here goes...
My job involved 80% sitting on my own, writing reports and messing with spreadsheets. The other 20% was dealing with people. The 80% bit was great. My ideal job would have been sitting in a room on my own... or even with other people and just working away. It was meeting and interacting with strangers that I hated.
My advice would be to make a list of the things you like... maybe solitude and repetitive tasks... and the things you hate. Break it down into bite sized chunks and see how it measures up to the job you are thinking about.
Then consider other issues... like...
Do you want to be challenged?
Are you happy to do boring repetition (it's easy but can actually become stressful in itself)?
Do you get a lot of self-worth/self-fulfilment from your employment, or are you not bothered?
Do you have lots of hobbies or thing to do at the weekend? I always lived for the stuff I did at the weekend, so the job wasn't that important to me for self-fulfilment.
