new job possibility nerves😅

I currently work at Sally Beauty Supply. I've been there since June and it was my first ever job. I knew absolutely nothing about beauty supplies (hair color,bleach,hair products,make up,etc.) but fell in love with my job.

the issue is, they only offer part time. I have an opportunity to work at Verizon (cell phone store) full time and make 9/10 an hour plus commission, but I'm beyond nervous because I know close to nothing ab all the technology they offer. the girl said I would do training for that but idkkk.

I'm really excited and I feel like it's something I would be interested in but I'm nervous that i wont pick up on everything or mess up somehow.

should I go for it? any advice? one part of me wants to go for it but my nerves and anxiety is really getting the best of me
