Do you work for all clients regardless or choose whom to work for?

[Btaliat]

There are some freelancers that don't have specifications. They work on the instructions of the clients. They don't select who they want to work with. Unlike some freelancers that are always given out their instructions. They don't work with clients anyhow. Rather they make sure that they only work with only clients that can comply with them.
