What more can I do? Guidance required

Hello guys

After one year doing a course which was meant to get me into medicine, things turned bad(as they usually do) and I have finally chosen to go and study finance. As my dad often tells me "water flows the path of least resistance", so I applied to a high ranked finance university in the UK and I was hoping if anyone could tell me if there's anything more I can do to get into a hedge fund as an undergraduate.

What I'm trying to do so far:

So far I have begun a trading account (spread betting) that will be profitable but the main aim is to show my discipline in following strict rules and never fighting the market when I'm wrong. I can trade many securities and currently in the process of learning how options work (will aim to trade them in a year or two).

I have begun an investing portfolio which I will write detailed long/short theses (with the help of WSO webinars) and explain why I chose to invest.

I have read a few trading books and I am now in the process of reading investing books along with other types of books also (book recommendations greatly appreciated).

I got a few businesses I'm trying to work on with friends and family, progress can be slow and only appears during holidays but I don't think hedge funds would care because some of these are just wacky ideas.

I aim to go to any summer internships I'm lucky to get into and may apply for the Amplify 2 month trading course

So I'm writing to you guys as a lost 19 year old who shocked his entire family (a big one) after his announcement of a career change. Hoping you could give me some extra guidance because I know I'm missing something and have much room to improve.

Don't worry I'm not doing this to prove my family wrong or something, I'm doing it for myself because I love the finance industry (being following since 16) and I have philanthropic goals which would definitely be accomplished If I get into a job such as a hedge fund employee.

Sorry for the long post and thank you for your time.
