What does it take to be a good actor?

As a person trying to venture into filming and documentary production my thought was like what does it really takes to be a good actor? What is that one thing that a person should not lack when pursuing their acting carrier, or filming directing or editing.

You can not just work up and assume you want to be an actor without something that motivates you to go on.

1. passion.
   you can do anything without passion. it is the fuel to drive you towards your goal

2. talent
   you got to have the skill if you are into filming

3. practice
   whether you have talent or not, practices always makes one perfect

4. connections
   connect with people with the same skill as you, it makes you realise you talent and passion and also gets you opportunities

5.believe
this above everything else is important. you got to believe in yourself that you can do it.
