That’s how you make an impact.
Thinking long term is what allows Google to invest in crazy projects over a period of years and then announce self-driving cars and glasses that project the internet direcly onto your retina (this article about the MotoX makes me excited to see what they do with smartphones over the next 10 years).
It doesn’t matter that you don’t have Google’s budget. Small efforts make a big difference over time. Dripping water hollows out stone, not through force but through persistence. Not everybody has a position of power or influence, but anybody can be persistent.
Life is long, and time is on your side, if you’re thinking long term.
