Here is a theory worth thinking about:
Shift your focus from long-term goals to ensuring high quality day-to-day experience that makes you get up out of bed filled with excitement and energy looking forward to doing things that you enjoy and respect.
Here is what I think is wrong with this theory:
Firstly, if you have the best day-to-day experience that is fulfilling and satisfying that makes you the happiest person on the planet, is that a guarantee that you will reach a great achievement one day? Will you keep floating around in a sea of great experiences that do not connect to any grand meaning?
Secondly, how would you find a great fulfilling and satisfying day-to-day experience anyway? To know what I mean by such experience check FLOW.
If you happen to find it, will there be any guarantee that you can always draw excitement and fulfillment endlessly?
Lastly, is finding such experiences about a lifestyle change or about a mind-set change? Is it about changing what you do day-to-day? Is it about changing how you see what you do and how you conceive the world around you?!
