GTA V activities not required for 100%

There are some activities that show on your checklist in the social club site that don't count for 100% and have little or even none effect on the gameplay.
Most of them you only need to make them once with any character for it to count as accomplished, others like watching TV may need to be done at least once with each character (Franklin, Michael and Trevor).
Note that there are a few more activities like this that aren't available at this point and that I'll make reference in some future videos.
