How many gigs can you do per day as a freelancer?

[Btaliat]

It is very obvious that freelancers are not the same. While there are some that can do as many as possible gigs per day, others can put a limit to whatever they can do on a daily basis. Some may be considering the time factors, other may be considering their capability. However, no matter the number of gigs that a freelancer is aiming to do on a daily basis, he should be considering how to satisfy the clients more. This will make them to refer more clients to him.
