Just got a second job, looking for help on how to manage seperate paychecks!!

I (18f) just got a second job (both are casual) and am looking for help on how to manage the different paychecks.

First job (Job A) paycheck comes in around Friday 2pm.

Second job (Job B) paycheck comes in around Tuesday (6:30pm)

Currently I have no active bills as I still live with my mum and do not have my full licence so share a car with her (so no insurance/rego YET)

I have had a “finance plan” for Job A paycheck for a while now, which has allowed me to save into a high interest savings, a car expenses account, and an upcoming holiday account while leaving me some spending money. I am not sure whether I should be treating each paycheck separately when they come in or whether I should be waiting a couple days to move the money around together.

I am also considering beginning to invest for long term savings (house, retirement, big holidays etc) so have started putting a very small amount away each week from Job A to invest a lump sum after my holiday (Early April)

As well as this I also earn tips and cash through gifts and things so have a money tin which I plan to open at the end of the year.

Does anyone have any idea on how I should be treating my paychecks? I’ve only ever had the one job so am not sure how to handle this, any advice is appreciated.
