How can I save $80 per month without the urge of spending it on useless stuff?

• best money market savings account
• growth money market savings account
• energy prices

I have $60-$100 of left over money but I get the urge and something inside that I

wanna use it to buy stuff that I don't need, like buying another PC or a TV I don't really need

just want.


Also, on energy drinks or shakes or ice cream.


I want to save $2800 to plan to buy a guitar later.


Is this easy to do?
