Yes. Shah Jahan built the Taj Mahal as a tomb for Mumtaz Mahal. John Adams relied on Abigail as his closest counselor across thousands of letters. Polish king John III Sobieski sent her passionate notes from the battlefield. George VI leaned on Elizabeth through war and duty. Devotion and greatness have coexisted plenty of times.
My only regret in life is not having kids earlier.
When I was 27 I was going out 4 nights a week, working 12+ hr days 6 days a week, waking up at 5am daily for CrossFit.
Kids would've been a breeze.
Don't wait for more resources to have kids. Energy is scarcer than money.
