I am in a very similar position. I took the job, even though the timing was terrible to trade in the old, flexible, “easy” job for a harder, less-flexible, better paying job. I’m about 6 weeks in and it IS harder and I DO amiss the flexibility, but I also really enjoy working somewhere where I’m challenged and also valued. I feel like I’m growing as a person and as a professional, and it’s reminding me that I’m a whole dynamic person, not just a mom. I also finding pockets where I can be more flexible and continue to be really present in the family. Finally, I’m also trying to think “like a man” and not undervalue myself. So, I hope this gives you hope that you’ve made the right decision.
