What are the worst things about being an RBT?

I'm accepting an RBT position and just started training. But I have another job offer and am debating which one I should settle on.

My RBT position is in a center where I will be given 40 hours per week and a mostly set schedule. 2 kids case load, one kid before lunch and another after lunch.

Other than that I dont know what to expect as far as stressors and challenges.

I seemed to click well with the first client I shadowed and it encouraged me to stick with this position but I want to make sure I know what I'm getting into.

Any help is super appreciated!
