What do you think of the bible saying that God prospers and blesses those who choose to settle down and have a family instead of being single?

When I was planning to get married and have kids I believed very strongly I'd make over 5 million and maybe over 40,000,000 with my book ideas which could be turned into 28 books cause I have so much data to go on. But when I decided that I thought being a wife and mother was too hard and did not want to get married, it was like, I did not believe I'd make more than $80,000 total from my ideas which took 16 years to come up with. One of the reasons I did not marry is that I'm scared of marriage and kids cause I've never been married and I've never had my own kids or any one else's kids either.
