Where do people focused on their careers find their partner?

Someone who is working on their careers, and wish to find their partners along the line of life, what actually are valid advice that work.

Considering they are working, have a job, going to gym, and also preparing for a better job in night. Avg looking people in the above scenario will be invisible.

If a person with above nature seeks someone with similar values, middle class background, self made through sheer hardwork, will also be very busy in their own life to improve.

From my side, work and studies take away a lot of my time, and I go to gym whenever possible.

I am 24M, 5 11 and a tier 2 Computer Science graduate, but I have nothing else other than my achievements, some hobbies of photography, sketching, writing poems whenever loneliness hits deep, have been declining time with time.

It will take me atleast 5 years to reach a respectable position at a good company with a good pay, strong enough to take the responsibility of family.

Till then either block my search or still balance everything or atleast try to, but if I am getting zero matches, what I even should do?

And repeated rejections have just fueled my own despise against myself, which is wrong, and I agree to it.

Looking forward to advise.Thanks
