Be successful enough to afford care.Yeah, but imagine yourself a single parent working two jobs to support your kids. How are you going to have the time and energy resources to do what you need to do?
Meet someone capable of helping you to raise a child.
Other than that, you might just have to do the best you can.
EDIT - I know there are single parents out there that have raised awesome kids. It's not impossible, just vastly more difficult.
