Life fulfilment/goal vent?

I’m 21 and when I was 18 I used to think I’d be fulfilled if I studied hard and got a good job. I’m now about to graduate with a degree at a 2.1 or 2.2 depending on my exam results. I’m going for a 1-year masters degree and then 2 years of studying/working to qualify as a solicitor before I actually start working. Despite my academic mediocrity (due to mental health issues, laziness and poor planning), I’m thinking of doing a 3-year Phd afterwards and then settling down to work for the MoD or the UN or whatever comes up depending on my employability. Does any of this sound viable or am I being delusional?
And then once I’m done with school, I just want to settle down, get married (arranged), have kids and be a homemaker while working part time. I’m not actually all that passionate about law but theres nothing else so I might as well go all the way.
Being in my twenties is just dreadful cause everyone around me either has a hustler mindset and is thriving in their corporate jobs, or chasing their creative passions, or nurturing their family lives at home. Meanwhile, I’m barely even studying for a career I’m not even sure I want, I have no passion apart from bed-rotting and everyone seems to have a dream or goal they’re chasing. TBH I didn’t even think I’d make it this far, it was supossed to end at 17 but somehow I’m still here and now I have to deal with it.
All I want is to make use of my education to get a respectable job with good benefits (i.e. pension), a fairly reasonable salary and to find some semblance of peace.
This was a rant but any advice or relation to anything I’ve rambled about would be nice.

You sound really well-put together! You must be a great planner as this is another level or organisation for the future.
Just curious, what type of jobs do you want to try achieving? (Also I was just wondering what’s your passion!)

That's exactly, what I don't want to be. Im 17.5. Same things will happen, if you don't act, just think alot. Here's a rule: If you want to know youself: "write".
There's something, a purpose, and that will Only be possible if you know what your truly are. There's needs and desire and wants. People want money, some wants pleasure (Kids and all~) some wants harmony and some wants peace'.
A good quote I have saved to give someone like you;
Don't be a copy of someone, be unique
-Einstein (He rarely seen giving life advices, but I got in his lectures, yeah) - There's literally and never will be someone like you, cuz the DNA 🧬 that runs through all your cells in your body is unique and will never be same. For time.
(another quote)
"in a world where everyone trying to make you someone else, who you are not, owning youself is the greatest accomplishment"
(Here's an advice, tho- just take it as kind knowledge) ----Drop a day and get written everything that you did in your life. And what your want. (Truly we don't yet know why we are here in the first place, haha) --im Still finding my purpose than going to uni doing a course and umm... Waste my years, then actually go and explore.

Thats true, thank you for the reply. Very humbling and reassuring when I remember that everyones just existing on random floating rock and we’re all individual beings! This is the first time I’ve really planned extensively about what I want my future to look at so putting action to thoughts is hard but necessary.
