You should totally try out thinking before buying. Lots of people are struggling with impulse buying and you are lying if you say that you are/were not one of them. People are addicted to instant gratification. We saw something that we want, we buy it right away. Sometimes without even checking the price tag. The price tag just becomes a question if you do have that amount of money with you. It doesn't represent anything anymore these days.

But since you're probably a guy who doesn't want to be so basic just like everyone else, you would actually want to think before buying it. Does the thing that you are about to buy actually going to help you with your daily life or will it actually help you at all? If not, then don't buy it. You have to know that you are not rich. You are not some first world country kid with some rich parents because if you are, then why would you even want to save money. Anyway, each and every purchase of yours should become an investment. Ask yourself if that thing you're about to buy will improve your life to an extent that you are willing to pay that amount for that little "upgrade" in your lifestyle. You can also ask yourself if that thing you are about to buy is going to be earned by that same thing as well.
