Kudos to you if you manage half time.
If you want to do it, see if your employer would allow it. Don't regret not doing so ten years down the track.
I like programming, but sometimes I wish I could do it only a few days a week and spend the rest doing something where I wasn't hunched over in front of a box 13 hours a day. Sales! Photography! Helping injured animals! I've never done anything that didn't involve sitting alone a desk all day...
I would probably agree with this a couple of months ago but I don't know any more. I just love meeting people, everyone is so different and interesting.
Your approach is great if the only thing that's going to make you happy is money and success but I've realised, only just lately for me, that it's not everything.
Just do what ever maximises your happiness and feeling of self-fulfilment. I'm sure money and success are great and can even be a source of happiness but I'm know if I was a millionaire tomorrow, I wouldn't feel content.
The second part gets a bit more complicated if you want to freelance or start your own company, but IMO you can still learn a lot early on "working for the man" that will help carry you forward in your own ventures.
I have never been happier.
Don't feel guilty about being subsidized. There's more than enough wealth from technology for everyone, we just don't know how to spend it properly.
I'm 21 and about to graduate. I totally relate to this and am already trying to adopt this way living into my life.
My friends often tell me I'm being unrealistic and I'll soon realise that I need to grow up.
My plan is to work part-time when I leave university leaving myself all the time I want to work on my own projects and to socialise. That's what makes me happy, so that's how I want to spend the majority of my time.
