Managing my money after getting corporate job.

Hi,

I’m on the verge of starting a graduate job that’d be 32000 salary, plus a starting bonus and an ote commission. How do I maximise this money. I currently would like to retire early (ambitious ik) but don’t want to waste my life penny pinching either. I want to strike a balance. I currently try to put about £100-200/month in a stocks and shares isa, and then the same in a stocks and shares lisa. Where do the pensions come in here? How should I navigate those? I’ll be paying rent too and council tax (I’m looking for bills included places). What is the best way to use my money? Thanks
