Dear HN,<p>I've recently finished my law degree, and I also have a degree in business administration. I've also turned 28 now. I have work experience in those fields (finance, law), but also in journalism and PR.<p>Over the last year I discovered that my career path (lawyer for financial institutions) really doesn't make me happy, in fact, all of it doesn't. I've come to realise that I lied to myself quite some time now.<p>What truly interests me and makes me happy is science and technology, ever since I'm young. Especially maths and biology. I just love it. I was too blind, to dishonest with myself to follow up on it professionally. Now I am honestly afraid it's too late, since I'm already nearing my 30th birthday.<p>So my question to you is: is it ok to start completely new? Pursue a degree in maths or biology, all the way? I'll be around 35 until I have a PhD realistically, because that's what I want to do, I want to do research and work on sometimes abstract and sometimes applied problems.<p>Or to put it another way? Am I too old? Am I still employable afterwards, with little work experience in that area so far?<p>Thank you very much, I feel lost.
