If you made such a comment on a date, I'd get up and walk out without saying another word to you. To be quite honest, you do come across as somewhat naive / self-centered to the extent where I need to ask if you've ever been in a serious long-term relationship. That, combined with the sense that you're approaching this from an achievement point-of-view, makes me think that you're in for a rough time. Relationships are complicated and kids even more so. Being a good parent is not something that can be taken for granted, it takes a lot of time and a lot of energy.
By the way, you can't tick the "working on yourself" box by doing "therapy, support groups, meditation, dating coaching, yoga and hypnotism". These are just activities, and I'd say at least equally prone to make you a worse person as to improve you. The best way to work on yourself is to be in a healthy, dynamic relationship with someone that doesn't think you're insufferable. The compromises and attitude adjustments you'll have to make to keep the relationship going are invaluable learning (and humbling) experiences that no book or yoga teacher will ever teach you. And this is my advice to you, someone who's in his early 50s, divorced, happily remarried with kids from both marriages.
It seems to me you're trying to dive before learning to swim. I would forget kids for the next 1-3 years, and focus on finding someone to be in a deep relationship with. Even if that doesn't work out, you'll be a lot better off afterwards regarding working on yourself. That will also make you a better parent.
