Preferably not something that involves criminal activity or ruins your health.
Doesn't have to be a job - if it is then you are either lucky or you have your ladder leaning against the wrong wall and will figure that out someday.
You could have a job you love/tolerate/hate and no life or a job you love/tolerate/hate and a life.
Try to go for the latter. Finding out you never had a life would be an unpleasant surprise when it's time to talk to St. Peter.
Sorry that's all there is - I'm not so good at wise thoughts. I find the older I get the less I'm sure about - except for some very basic stuff about things like naps, sun, water, air, food, dogs, movement, learning, laughing...
