Oh, how I feel you...

I can really relate to the feeling of wanting to spend it all at once, but I do consider that's a psychological behavior we've developed by the Venezuelan crisis. When it comes to my expenses I just try to spend the least I can in everyway. I also feel very uncomfortable when almost emptying my wallet because I feel like all of my effort just goes not really invested in anything, only on food or things that won't give an actual income for spending on them.

But alas, not everything is lost. One tip I would recommend you consider is.... to not always go for the thing with the most 0's on it. Ask yourself if you really need what you're about to buy. (That's my only excuse for buying food) Always go for what you need, not what you would like to get if you were rich, because you're not. I'm not and also most people aren't rich either. If we always go for the things we desire the most, we'll probably run out of funds rather quickly, so there's that.

Hope this helps you even a little bit!
