From my bystander's standpoint, having a child is often the best WHY to drive MEANING and PURPOSE. It be a shame if they became an excuse.
I agree with this and a lot of the comments that have been said so far. I have been a motivated individual for most of my life and then a personal "failure" happened and I pretty much just went into maintenance mode for a few years. My wife and I have recently had a child. That in combination with reading "Unscripted " have been huge factors in me turning things around and making something more of myself than the conventional norm.
It is a life-changing event my friend, but it is also manageable. I work a full-time job and have started the beginning stages of building a business while completing two educational courses online.
The motivation and determination to achieve a high level of success will become the standard now, as most of said on this forum that you want to be able to provide the best quality of life for your child. I believe this includes the ability to teach them how to create freedom early on and be able to generate income outside of the 9-5.
Also don't forget you have all this time before the baby is born to get things rolling! Take advantage of it!
