idk why but this last month (september and october) i lose my ideas and habilities of the mapping, i not feel nothing for the mapping like a few months before, nobody dont feel the same thing? 

Puberty 

Don't sweat it man, it happens about once a year for me. You'll take a break for a while and after a few months you'll feel the spark again. If not, it's time to move on to something more exciting

I usually take a few days off just to do different things. Right after that I'm back to work on something.

Yeah, like deathclonic said. Take time off mapping, just don't worry about mapping or making progress, and just do other things. Perhaps learn modelling so that you're still around the modding area and you don't lose it completely. That's what I did and recently I'm getting more and more back into mapping. 

thank's for the help people  i going to think about this problem 

try doing something (mapping related) that you haven't done before?

he just said he's bored with mapping and has no motivation and you say do more mapping. 

what i was getting at is doing something new that is mapping related.

say he was just making random brush's in radiant (for whatever reason), and got bored. maybe he should make the map instead of create random brushs (bad example i know lol)
