ELI5: How does methylphenidate work on ADHD brain?

I recently got diagnosed and medicated. The meds work absolutely awesome - I can hear a real silence, I can have a clear thought process instead of something like 5 radio stations and 4 news channels on in my head, I am less anxious (normally I cried my eyes out when someone in work was mean to me and I didn't want to go there again, would call myself useless and worthless, now I can just shrug it off and go on), more self confident, have energy to do stuff around the house and feel more calm but not tired in general. 

I know the meds work because they do something with the dopamine retake, but I don't really get all that complicated words and process. I need a REAL ELI5, maybe ELI8 (like, say that dopamine is a pair of jeans that the neuron uses and gets holes in it? I tried to explain it to myself kinda that way but I wasn't right probably).

Your brain makes dopamine and tidies it up when it's used.

Dopamine makes your brain work, but people with ADHD don't have enough.

Amphetamines & friends make your brain make more dopamine so you have more available.

Methylphenidate slows down the tidying up, so you have more available.
