How to Activate Face Book follow on account

I currently have 4800 freinds on Face book and nearly 1000 outstanding friendship requests.
My friendship limit is 5000...

Further, I have not been able to switch on the following feature on my FB. Everyone is a friendship, want to convert some to following..

I do have an Instagram account as well and a linked in account..

Objectives;

1) Switch on follow on my FB account

2) Work out a strategy to get my current friends / outstanding friends request to follow instead

3) What to be be able to publish post on all social media platform at the same time

4) I have just started a personal youtube channel
5) Any ideas of how we can work going forward to grow my followership
