I've been thinking 30 has been hard because unlike 10 and 20 the benefits of aging do not seem as clear. This could be completely subjective to me, but I think this is why it is common.

I do not and am currently single. I do believe that if this wasn't the case I'd have been able to appreciate the milestone a lot more.
Children bring a level of joy to the aging. I strongly believe that.
