Look to the people around you; the people you interact with every day; the people you walk by; the people who serve you your coffee, drive your trams, who sit next to you in their cars in traffic. Look to your family, your friends, both close friends and distant. Look to the people who have given you a helping hand in your life and those who haven't. Look to your work colleagues, your school mates, your Facebook friends, your 'followers'. Look to the children who see you as you go about your daily life.
Look to the environment around you. Your house, the street you live in, the roads you drive. Look to the things you use, the things you buy, where you spend your money and time.
If you are not making every effort to make the lives of all of those people and places better for having had an interaction with you, calm your ambition of 'changing the world'. Unaccountable, gigantic goals are easy to proclaim. It's easy to say you want to end 'mental health' problems and still be an asshole or even simply indifferent to people you interact with. It's easy to want to help 'the children', and not make an effort to teach the children around you with your effort and example. It's easy to say you want to 'save the environment' while driving for an extra 10mins to find a car park, buying new disposable goods all the time and constantly consuming for the sake of keeping up with the Joneses. It's easy to say that you 'love learning' and never read a book, engage in deep discussion, or test your ideas out with people that might challenge them.
Positive impact of any kind starts with your immediate circle of influence and works it's way out, not the other way around. Lead by example and be the person you'd want to interact with, the person you'd have wanted to meet and know when you were a kid and be a person that decides what effort looks and feels like on a small scale before worrying about how you're going to change the whole world.
I love a big goal as much as anyone, the @jbnproject is testament to that, but we need to encourage impact from inside out, not outside in, or we are never going to get where we need to be.
As always, lots of love - Josh
