Do you think your 30s and 40s are the most stressful? You would have way more responsibilities than you did in your 20s, but fewer resources than you have in your 50s and above. I am in my very early 30s now and things feel stressful. Careerwise, I have somewhat established myself in the trade, but it also means I have more responsibilities and have to answer for more stuff at work, while I am not at the comfy upper management level yet. Familywise, I just got a kid so more responsibilities at home as well. I have gotten jaded at work, but cant quit in this economy and cant with coz I have a family now. Things just feel more stressful than the free and easy 20s.
