Real Estate Agent- Transition from p/t to f/t agent

[Jack Exum]

I have been in education for 22 years (full-time), and a real estate agent for 2 years (part-time primarily). I got out as an agent due to some family issues and get back into education out necessity. Now my family situation is changed and I have reentered the real estate field as an agent (part-time) looking to convert to full-time once I have established the processes and maintained a consistent pipeline of business. My question is what advice can you give about when to make the transition to full-time real estate. Is there a "tipping point" where it is more of the right time to do so? 

Also, what are the "big rocks" to focus on to make that goal of full-time agent a reality?
