Try out this strategy, strike things quickly out of your need/want list and be content, so they no longer become a problem and hindrance to your plans to save/invest.
If you plan to buy a house for your comfort, and it is within your means, seek out a way to get it done quickly.
If you plan to get a car, as you feel you are ripe enough for it, and there's a means to get it, don't hesitate, get it quickly off your list.
if you plan to buy a home equipment, electronics or furniture, and it is super important to you and your comfort, buy it and get it off your list.
The longer you wait at times, the more prices increase, things are not getting cheaper, the longer you wait the more the thought of this need bugs your mind.
Well for me, invest first before you buy those things that you want. I'm a teenager who's suffering from financial crisis and having a 3rd world country is making it much worse. Reading and watching youtube motivational videos also makes me disagree with you. Lots of my followed financial advisors in YT preferred to invest first before buying things. 50/30/20 rules applies as well.
