<human>: This is my first post here and I hope it adheres to the rules of this subreddit. 

I've just finished university (UK) and I'm looking to begin saving/growing my money as fast as I can with minimum risk. 

I am starting a new job soon which pays me £18,000 annually for the first 3 months, and £20,000 after that. I have around £8,000 in savings. And I currently live at home with my parents, who do not charge me rent.

I've read most of the sticky posts and FAQ's on /r/personalfinance, and I've been looking at different types of bank accounts/ISAs/Bonds to determine which is the best option for me. 

Aside from this and cutting my expenses, I'm looking for other ways to quickly save money so I can eventually put down a mortgage for a house/apartment with my girlfriend. 

I mentioned earlier that I'm looking for minimum risk investments, but I was looking to invest around £2,000 in stocks. Is this a good idea? and is the amount worthwhile enough for me to invest in stocks?

Can you summarize the given text in a few sentences?
<bot>: are stocks worthwhile buying into for me in my financial position? and are there any other ways to save/grow my money that I'm missing?
