What is the best way to become FIRE?

Hi all,

I'm very new to this topic and start learning about FIRE. I lived with my parents and don't spend much so I've saved most of my salary in the bank. While I realised I could probably do some investments rather than only savings. But I do not have any experience in the stock market. Hope it is not too late to start now. Would like to seek some advice based on my situation.

Background:

I'm 27. Working as a software engineer with £62k. My company offer a flexible benefit, so I put the amount into the pension. My employer is paying 9% and I am paying 5%.

Investment:

£4k LISA - I got my LISA last year, and just received the £1k bonus

£1k PB - Not sure if it is a kind of investment, as I never won a single prize

Assets:

Cash - £100k
