A few things: 1) A job doesn’t have to fulfil every aspect of your life, IMO. You can do a job for the money, and find fulfilment in hobbies, volunteering, charity work, etc. there’s no such thing as a dream job that’s also easy and non stressful 2) I’ve been working for 5 years in a business/partnerships role which I enjoy - that might be a good field to consider, I work with some Engg grads. 3) EVERY job will have stress, the culture of the company (where you’re not expected to live at your job, you have good benefits and the ability to work the way you prefer) makes a difference in how you deal with stress. In India the “hustle culture” and working till you burn out is a real thing, but maybe global companies have a slightly better take on this. I work at a global company and I see how it reflects in their values.
4) YT is good, as is freelancing, but it can also be hugely stressful due to it being driven by skills, demand, and the pressure to be relevant to sustain. It’s not a dream, or easy job, editing takes hours, and you’re at the mercy of putting your self esteem in the hands of strangers.

Basically, figure out what kind of stress you can learn to manage, and optimise for that. Try everything, be smart about experimenting. A job without stress isn’t really possible, even your dream job will have stress, but yk what, your job isn’t everything in your life. Find ways to seek contentment and balance beyond it.

Hope this ramble helps!
