Yup. I guess spending time with family and friends makes it better. At least it does for me. We adopted a dog with my girlfriend this January and I'd say that just spending time with him alleviates it. I'd imagine having kids will have a similar effect (probably 100x stronger).
In the newest Indie Hackers podcast [1], founder Aline Learner mentioned that starting a business helps with existential crises because you're so busy worrying about everything else. I'm looking forward to finding out if this holds true to myself in September.
