How do you deal with multiple projects and multiple clients? I generally juggle three to five projects at a time. However, my business is showing rapid increase these days and some times I think all the plates (or balls depending on what I'm juggling) will fall.

Do you 1) handle one project at a time and put the others in a queue or 2) work on all of them simultaneously?

If you #1, then what do you do about long-term clients?

Any input would be greatly appreciated!
