How do I get better at making decisions and what to do for the future?

So basically my birthday is tomorrow and I (M24) will turn 25 and I have been thinking all day about my future. Short story on what I mean: I am more on the extroverted side, but also do game a lot with friends on my pc. I've lived together with my ex until I was 22 and after we broke up, I went back to my moms place, and am here ever since. My current problem is, making the right decision on one specific thing, and as well as making future related decisions, like for example financial decisions. The specific thing I can decide on is: I live in Austria and my 3 goals as of now are: moving out, buying a nice car, a 1 month trip to Japan. The problem is: a 1 month trip is very expensive, and moving out would also be important, since I slowly have to think about getting a gf and settling down, no? And I love cars and would like to buy a car on the more expensive note as well. But when I move out, it's gonna be way harder to save money for a car and the trip. And when I do move out, do I just rent, do I try to save money for longer and buy a real estate? It's so hard to decide on those things. And for information, my mom would literally let me stay here for ever as long as I pay rent and it is not as much as I would move out.

The normal decisions also intertwine with the problem from above, since I am a really "living in the present" guy. I am a software developer and I would say, that I have pretty good salary. But saving is sometimes hard, as I am a "present" guy and when I see something I want, I don't really even think about it and buy it. Doesn't matter if it's a new phone, or even microtransactions in a game.

So could you give me any tips, on how I should organize my life more and how I should go on about my future and what you guys would do in my shoes? Appreciate every one of you
