Is there an ending to this pursuit ?is it good for the growth?

Is materialistic pursuit bad? I have observed since an early age. The thing which i yearned for , as soon as i got it. I lost interest in it. I wanted a bicycle. Got it then stopped riding it . Wanted a 2 wheeler , got it , again lost that feeling of newness after sometime. I used to be so eager to drive a car . Now when i have to drive it daily, it doesn’t give me the same joy as before. Got into one of the most elite colleges in country by cracking the entrance exam. Now this achievement feels like nothing special there are hundreds like me.

I want to become a billionaire. I know when i will become one , that achievement wont matter to me that much .

So my question is. Is this relentless pursuit of things good because this motivates me to achieve the next best thing. Or it is stopping me from being happy.
