intelligence

 
Do we gain intelligence or intelligence comes from gene and we can't gain it?.  If we say intelligence is something that we receive from our parents by gene that mean our brains don't improve. I believe intelligence is something that you could gain by working hard. Talent without working hard is nothing. I believe also working hard without talent is zero. So we do need both of them. From these point I can elaborate how intelligence is connected with hard work. So, there is a factor between intelligence and working hard. Your intelligence improves according to the things that you do.
