Working in a laser surgery center

I am just offered a job at a cosmetic center. I will be working with a surgeon who will train me to do botox injections and laser treatments. Needless to say I am super excited about it.

At the same time, I am offered another non-nursing job (lab coordinator) at a clinical trial research center but the job involves EKG interpreting, blood draw, stool sample, lab results, paperwork. I am more leaning toward the first job at the cosmetic center. I am a new grad with only 2 month experience in a cosmetic/medical same day surgery center ( this is my current job but offer too little hours hence I gotta seek for a second income). A little about my personality: I have low tolerance for stress and cannot handle the pressure working as a floor nurse in the hospital setting. I want something routine, less workload and don’t mind to be paid a little less and/or without benefits. I just need something stable.

Please help me to choose between the two. Thank You!
