Same Old Brand New "eyes"

Title: Same Old Brand New "eyes"

through a new pair of "eyes", i have seen the world like usual. Well this pair of "eyes" makes up of 2 black supporting flat rods, with a front view of pure white color and rectangular shape. Yeah, it is my new spec. But with this pair of new "eyes", the feeling differs. it gives off freshness and new level comfort. That's the differentiation it has for now. However, i have come to understand that the freshness may die out after some time. This is applied well in the concept of economic and business. First a relative new business of unprecedented idea will first experience a stage where there is no growth, then entering the second stage - the growth stage. This is when there is exponential growth and increase in market shares. The third stage is when the market matures and so everything cools down. The last stage - shake-out - will see business leaving the market. That's as good as expressing the freshness dying out. Comfort cherished now will be got used to and taken for granted.

That's human, i guess. Have i always been like that? Have you too? What is it that can really maintain its competitive advantage which nobody can ever leave it out? Is it an object of sentimental values or tangible?

To add to what i have in mind now, it is the complication that bothers me. Motivation needed now.
