Embrace Change.
For the sentimental: Only then can you live your past.
Only through change will you be plunged once again into the unknown from whence you started, and in which you flourished and survived.
For the brave: Only then can you taste the present.
Only through appreciating change will you be able to see that nothing is eternal, that every piece of the past and present should be treasured and remembered.
For the idealist: Only then can you create your future.
Only through understanding change will you be able to wield its power on society, use it for societal benefit, and change the world, your future.
