The most important thing is to start with yourself and cultivate character. All your future actions will be more effective if your foundation is sound. How do your daily actions affect other lives? Think about your food, your transportation, your consumption habits. How good of a designer, developer, salesman are you? How much time do you spend a DAY learning, building, pitching? Don't waste your life trying to change the world without changing yourself first, this process will also change how you see the world as well.
So start small, stay grounded, and grow stronger with age. That's exactly what I did and am still doing. I am going to enroll in Startup School and apply to YC soon. If they don't accept me, I'm also applying to both HackReactor or Galvanize Data Science. I also plan to hang around Stanford and Berkeley to make friends following the same moral, intellectual, and creative compass. The plan is to 'get so good, they can't ignore me'. I'm going ALL IN on my hope that humanity can still live harmoniously with our home planet and expand beyond it.
If you're for real about this, over time you will get to this level of urgency and do what is needed for you to live in accordance with your conscience. Earth will be fine whether or not we decide to live harmoniously with the rest of the biosphere or not; when the Sun dies, the rest of the galaxy will take thousands of years to even notice. So try to be humble, I still struggle with this seeing the state of our planet but lead by example and whoever is ready will follow.
