You didn't quit your 6-figure job to sit on the sidelines for 6-9 months as you learn how to do deals.
You're not burning your nights and weekends and free time and lunch breaks to sit on the sidelines and not be successful.
Your family can't survive forever while you learn.
Your savings will eventually run out and you'll have to give up, go back to your job, and admit defeat to all those you told "you'd never go back" (the story for full time searchers).
Your nights and weekend efforts will always be less than the full time searchers so you must figure out a way to be more efficient with less time before your time is up and you have to admit the same defeat (the story for part time searchers).
