I'm not a good source of investing advice (other than "do it"). In general you need to treat it like any other skill you need in your day job, including deciding which skill(s) to learn. Investment choices are going to depend on your life and interests.

There's been a lot of discussions here on HN, that should give you some ideas (not advice).

I understand you can invest in New York City taxi medallions, which have done nothing but go up in value. But that's not advice, just pointing out how wide your choices are.
