Disclosure: I have an RE license
It all depends on your state. Some states have a long process for getting a license, others do not. So, if you want to start now (because it takes a year) then yes, you should get going on it.
In my case, there were some laws changing in my state that would triple the time requirements to get a license. So, I got in just under the deadline, took the exam, and got my license in a fraction of the time it takes now.
Your first call/website should be the DRE in your state to find out what the requirements are.
