Live in the present and enjoy the moment because that’s all we really have. It’s impossible to “have it all” ― so ask yourself, are you happy with the way things are? If not, then by all means, try something different! Because there are two paths you can go by, but in the long run there’s still time to change the road you’re on.


I like to build models that predict future investment returns, and I’m fascinated by world events and constructive political dialogue. I enjoy growing flowers and vegetables, building music playlists, and quoting song lyrics as though they’re my own.
