My sickness, future and PlayStation 2

I am sick. For last few days. Not metaphorically but really. Lots of cough. Weather change. Usually I get back to my normal self within few days. But this time it's taking longer than usual. A whole day of sitting in AC certainly doesn't help me. And to avoid coughing my guts out I have to take liberal amount of cough syrup in office. That makes me sleepy as hell. Very tight situation.
Anyways. As I was saying that I am sick. It's sickening. Really. I can't eat ice cream. I can't drink anything cold. When everyone is having cold drinks and other stuff, I am drinking hot water even when there is scorching heat. Not that I like cold drinks. But still. By the way I don't know why but I don't like them.
Also I can't eat pizza. It has got nothing to do with my cough (ok...a little) but because I am trying to avoid junk food.
Why do the most desirable and pleasurable things in life tend to give us either heart attack or cancer or AIDS??????
lolz. Just kidding.
It seems like I can't do anything of my liking these days. Which reminds me of my another dilemma.

When I started working I had two specific objectives.
One to pre-order the seventh Harry Potter book. (Which I did just a couple of days back. Yappie)
The second one to buy a PlayStation 2. (I know that PlayStation 3 is out but I still prefer PS2 partly because it runs every game that I ever wanted to play and partly because I can afford it). I am very close to achieve that objective. Just a few weeks more and I'll have it.
But as it turns out my dad has plans for my money. No surprise there. He always has plans.
This will help you in future. That's his usual punch line (Here punch line means the line that hits me in the face like a punch). I agree with him totally. Usually I go with him. And here's where the dilemma starts.

I have been dreaming about PS2 for years now. Dad never bought it because he really dislikes gaming. Thinks it's a waste of time and money. Specifically in my case because I have no control over myself when in comes to gaming. Totally agreed. I am a complete waste in that regard. Or rather I was. Now I am a lot wiser (What an achievement!!). And that's why I want to buy it. It's really important for me.
If I go with dad my plan for PS2 will be postponed for god knows how much time.

Is it really necessary every time to care for the future at the cost of present?

My heart's desire versus my brain's logic. The age old battle. In the past I have nearly always listened to the logic. And I have rarely regretted it. I am just too much practical. Can't help it.
I can always buy PS2 later. But will it be really desirable at that point? Will I really want it like I do now?

Next few weeks are going to be tough. What do I do? What will I do?

I really need to read Rich Dad Poor Dad again.
