23 Years Old - Advice for FIRE?

I’m 23 years old, based in UK, earn around £30k per year at the moment (take home £26k ish after tax).

I currently put £110 per week into savings, which is sitting at £14k at the moment, but will go to a house deposit when that time comes (likely in next two years). I have around £2k in the S&P500, but I have stopped investing in this until my spending account reaches £3k, which I will soon treat as my new “£0”.

I like the idea of FIRE and do follow the basic financial “baby steps”, but unsure my salary will allow for FIRE.

Anyone any advice for getting ahead early as I like to think I’m still young?
