A major life changing decision

So I've decided to literally save every penny I can by not buying any more food or paying my power bill or making any unnecessary purchases and by literally picking up any change I see on the ground, for example I was walking to work one day and I seemed full since on the ground and picked it up, until I have enough money saved up and pay off my ch*ld support and one enormous lump sum. I don't know if this is a good or bad idea. And I also don't know if it's a good or bad thing that I posted this idea because it might backfire. It seems like every time I try to do something positive and I let somebody know my business it backfires.
