> Also, in my exp your manager, boss, lead has alot to do with the amount of stress.

To explicate a little, I've found stress mostly relates to the expectations of people around me, and has very little to do with the difficulty of what I'm being asked to do.

That's literally the definition of stress. Stress occurs when you feel that you cannot (or just might not) meet the expectations set on you. The expectations can be external or just come for yourself.
