Reignite that passion of yours

Thinking about some stuff while shopping alone to kill time before FAC Finals briefing ystd.
I finally saw that something that i wanted to get long ago but just because it's kind of exceeded my budget by a bit, after considering, i put it back and walked off.
Don't you feel it ironic?
Whereby you felt kind of excited at the moment when you saw it and in a few seconds you felt like nah, it's ok. I give up buying since i've been searching for it for so long, i don't mind looking for it at a cheaper price elsewhere or probably i've lose interest in it.

Relating it back to life, it seems like what i've been discussing about is more or less similar to our passion for things.
It's the same. When you just started doing something or liking something, you'll feel passionate about it. You'll give your all to make sure everything runs the way you wanted it to be.
But after years or even months, you might get tired of it especially if there is a particular reason to/for it.
I do believe that passion can be ignited again but it also depends on various reasons.

I really admire those people who have burning passion for things especially when that passion never dies for a very long period of time. I guess i'm trying to be like those people. Maybe i'm trying too hard? Till i don't know if i'm doing it cause of passion or just a sense of responsibility.
