Moxie Marlinspike:

As a young person, though, I think the best thing you can do is to ignore all of that and simply observe the older people working there. They are the future you. Do not think that you will be substantially different. Look carefully at how they spend their time at work and outside of work, because this is also almost certainly how your life will look. It sounds obvious, but it’s amazing how often young people imagine a different projection for themselves. Look at the real people, and you’ll see the honest future for yourself.
