It started 3 months ago i have spent 500 dollars on diffrent kinds of puzzles like rubiks cubes "twisty puzzles" i cant get it off, im playing with it night and day, im not sleeping im solveing it, in scool ,in shower,while in bathroom everywhere, im playing with it.......... is it normal ?

Though I can't remember how to solve them anymore... I think you have to learn that some time and keep on practicing to not forget.
"in school, In the shower, while In the bathroom, everywhere.. I'm playing with it."?
I don't understand where the fun or challenge is in that. To me it's like doing a crossword by just transcribing the answers from an answer sheet.
We live in such a strange world where we gift "achievement" for little effort and nobody is ever stretched or left disappointed by failure (leading to a will to try harder).
And then we belittle the achievements by reinforcing how things have become easier (exams, for instance). I would hate to be a 16-year old in the world today. They are being failed by a generation that wants them to think they have everything, when really they're given nothing.
