A crash course in changing the world.
There are a few ways to approach this, and a simple google search unearthed at least two perspectives:
1) Life progresses at different speeds depending of who you are. Environment is important here, and for instance the difference in access to information and resourceful people can mean a lot if you want to do a project. The banal example could be: Getting water by turning a tap, or getting it by walking 1 hour to get to the nearest well. Water is the simple example - others could be access to information (library, a computer with internet connection), or even access to knowledge about what information IS out there which might be relevant for you. As Samuel Johnson famously said: "Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it." Your world moves at different speed depending on how resource ful you, and your network, is.
2) The earth movies physically at different speed in its rotation depending on where on the globe you are. This is a much less interesting solution, for me, but is true.
