I've sacrificed my entire career so that I can take be the primary caregiver of the kids, and my wife can concentrate 100% on her career. During the pandemic, I quit my job and concentrated solely on the kids, and now that the pandemic is over, I'm at a much less demanding job so that I can do all the pick ups, drop offs, homework assignments, etc.
I love it, and I feel truly lucky that my life has given me the opportunity to focus on my kids.
