Choosing the Right Path

On average it takes a photon 40,000 years to travel from the core of the sun to its surface, but only 8 minutes to travel the rest of the way to Earth.  
As each photon travels, it is briefly absorbed and released by atoms, which scatters it in a new, random direction. To travel from the sun’s core to the Sun’s surface (696,000 km) so it can escape into space, a photon needs to make a huge number of jumps.
The calculation is tricky, but the conclusion is that a photon takes many thousands (and sometimes many millions) of years to wander through the dense matter inside the Sun to the surface. Theoretically, some of the light that reaches us today is energy produced millions of years ago.
Choosing the right path in life is can be just as tricky. If you want to get to your goals it is best to work on direct paths rather than bouncing from place to place.
