No I don't think that everyone is talented. That's the sort of thing pushy parents tell their precocious kids. It's a cute idea but nonsense.
Talent is rare - that's what makes it special. I agree with Mikey - it's overrated and, to most people, irrelevant. Most people why are good (I mean REALLY good) at something began by coming across something they were interested in; something they enjoyed and then they worked hard to become better at it.
A person needs to have an aptitude for something to do well at it. For example, I have NO aptitde at all for anything connected to sport or athletics. On the other hand I do have an aptitude for musical things and, to some extent, artistic things in general. But, I have no talent at all. I found learning to play guitar VERY difficult and I am, at best, an average player. Talent would have meant that I found learning fairly easy and/or I would be, by now, a truly exceptional player.
I think you are mistaking "talent" for aptitude, skill or ability. Being able to make a person laugh or or write stories or play piano or paint etc.) are NOT talents but a person could be talented at any of those things. That would mean they found it unusually easy of were exceptionally good at it without needing to make the same amount of effert as a "normal" person.
