Make money quickly with things?

How can I make money quickly as a 15 year old (still have to go to school). So I actually have an idea and sell my things I have, for example. A Ps4, 3, 2 or my cell phone (iPhone 8) because I'm saving on an iPhone 11. Will the things bring me a lot of money if I sell them?

Not really. And why do you need an iPhone 11 at 15?

Used PS4 about 145 euro

PS3 50 euro PS2 10 euro

iPhone 8 about 400 euro

Believe me, Iphone 11 is not worth it. Keep the 8th

Do you name the offer?

In principle, I think it's good if someone has wishes and dreams and works towards achieving them!

You just have to check for yourself whether you want to accept these privations for the goal at time X and the experience / advantage / goal is worth it.

What can the Iphone 11 do better and better than the 8 and what do I really use.

Is it worth to me that e.g. No friends come to me to play Playstation.

Regardless of this, you can think about whether when you buy the PS4, you sell the PS3 promptly if you still get some money for it.

Then you might have saved enough money at some point to finance an upgrade.

Think about it…
