Impulse buyer

Ok let’s just be honest, this quarantine isn’t helping here. I have a lot of bad habits when it comes to money and I am looking for some advice.

I pull in decent money every month, definitely not struggling nor living check to check. Howeverrrr, I’ve racked up my credit cards/no money in my savings. And I’m really trying to look into my future and trying to have kids soon. I want to be a role model and have my crap together...

I created a budget plan to help me stay on track of my goals, however not even 1 week later I purchase a computer $1400.

In my favor, they are out of stock, so I cancelled the order. But at that moment I knew I never needed to buy to begin with.

How do I tell myself no?

How do you determine if something (of a higher price value) is something that you actually need or want?

Do you think about higher cost purchases before you buy it?

How much is a higher cost purchase, to you??

How do you stop yourself from buying something you don’t need to buy?

Anyways just looking for some advice. Online shopping is my issue..
