Do what you want the most first. If that means putting your effort into your family, then do it. You can always go to school at a later time, but you cannot wait forever to have another child.
The big secret is out regarding CRNA earnings. And the temporary shortage is not going to last forever. It seems like everyone is talking about becoming a CRNA these days, from high school seniors to established nurses. I attended nursing career fairs and nursing school
orientation sessions during the past few months. The instructors, school staff, career fair staff, and potential students are all talking about this nursing specialization MORE THAN ANY OTHER.
When there is this much interest in an occupation you can be sure the good times will not last forever. But try to tell that to people now--especially those too young to have lived through a temporary labor shortage--and they will not listen. They are too focused on the present to look at the future and the fact it takes years to get to the goal. They fail to recognize that labor shortages are ALWAYS temporary and that there is a limited window of opportunity.
I am 45 years old, and there has never been any occupation in my lifetime that had an employee shortage for more than a few years. News about the shortage eventually becomes widely circulated--as is happening now with the CRNA. Then the applicants arrive in droves wondering what happened and why they cannot get a job.
Come back and re-read this post in 5 years--approximately the timeframe you mentioned. I won't ever forget that I wrote it. Yet, I would be willing to bet there are dozens of others reading it that will claim 5 years from now no one ever said the shortage was temporary!
