Am I making a mistake leaving my my job?

Basically currently am a college student working full-time and retail and I ended up getting really lucky by getting this job because it does pay well. I make at least $26 an hour that’s just adjusted due to commission. and I really want to go to veterinary school animals in general and in order to do that I need to get experience in in order to go to most vet schools. You need animal care experience, especially if you’re not a stem major. I got a job as an assistant manager at a pet daycare center, which will get me Mike’s animal experience in order to get other jobs and as well it’s only three days a week 10 hour shift but it is $17 an hour now all I have to do is pay for my car insurance as my car is already paid off and I don’t have any bills, but I told my mom I’d help her with the surgery that she has to get, but I do have a lot in savings and I feel like three days a week will be perfect because I can have two days for school which I don’t have now I’m not able to do schoolwork at the job and it’s not flexible at all, and I can set aside another day additional in order to work with equine or wildlife as a volunteer or something. I don’t know. I feel like I might be making this mistake but I think I only think that because of the pay I don’t know I have it till tomorrow. Let the lady know but I feel like flexibility wise. This might be the best that OK and most animal care experience shops don’t pay 17 hours starting with no experience so I don’t know sorry.
