How to add more than 5 tasks to a workflow?

How to add more than 5 tasks to a workflow?

I am new to workflow and have a process that requires more than 5 tasks.  Can I do that or do I have to break it down into smaller workflows?  I see all of the tasks listed in the tasks tab of workflow.  However, when I click on the work flow rule and try to add another task I get a pop-up that says I can only have 5.  I'm confused.   
Thanks
