Should you work as a CNA/Tech before or during nursing school

I have been thinking of working during nursing school and may seek employment as a CNA or Patient Care Technican. What are your thoughts on working during nursing school? I do not need to work during school; however, financially it will be ALOT more comfortable if I do so. Also, I never worked on a hospital floor and read that working as a CNA in a hospital will be beneficial. Some have said nursing student who were not CNA or techs prior to becoming a nurse may struggle with time management skills and have a slower time learning skills. Do you think it is important to work as a CNA/tech before or during nursing school?
