IB the best career springboard for me?

After using this site for a couple of years, I thought it'd be a good time to finally post. A bit about me - I'm a second-year student in what could be described as a semi-target European uni for reference. I've seen a few really good career-related posts of late by older WSO users so I thought I'd add my 2 cents on my own rough plans to see what opinions/ advice people have - I'm guessing there are a few students in a similar position also. 

Basically, I've always been interested in markets, business news, current affairs, etc., so ibanking has appealed to me as the best way to start my career for a couple of reasons - I'm good with both numbers and people and try to maintain a lot of different interests both socially and intellectually. From what I've read and heard from those in the industry, IB is a great place to combine these people and numerical skills while working alongside people from any number of backgrounds. Also, I'd be able to develop and showcase a great work ethic early in my career. In my twenties why not try and push myself, I know how valuable the brand/experience/network of an IB stint can be to any future career I may pursue. I think also I've done well academically to this point without pushing myself hugely, so a job where I'd be pushing myself alongside really intelligent people appeals to me a lot. 

Long-term, I think I'd love to start and build my own business, and the skills/ network/ industry-specific knowledge I could potentially learn from banking would make it a great place to start with entrepreneurship in mind. I'm reluctant to try and go out on my own too early in my career as I believe the aforementioned benefits of a stint in banking would stand to me down the line, and who knows, maybe a 'conventional' finance career path ending up on the buy-side (if I'm lucky) may appeal to me then - so, therefore, going into banking gives me the greatest breadth of career options in this regard also. 

I think it's important to mention I'm not obsessed with making as much money as possible, either. I genuinely want to end up doing something I really enjoy. Yes, I know banking (namely M&A) seems to be a slog at times, but I think the work would genuinely interest me, and if not, I can leave with a  great brand on my CV and lots of options as I've said. 

Just to add, in case anyone is thinking 'you have to get into banking first' of course, I realize how tough it is to break in, but this is just a hypothetical scenario. I've done a couple of spring weeks already so I feel I'm on the right path to hopefully doing just that.  

I'd love to hear any opinions or perspectives on what I've said above, especially about my 'ideal' early career path given my potential long term aspirations. What would you tell your younger self if you were in my position? If you're a student like me hoping to go into banking, please drop a few of your own thoughts too on mine or even your own situation. 

Hoping this doesn't flop! Thanks
