I think it's important to understand perspective as well; I would consider reading Keller's Millionaire Real Estate Investor AND Agent books to understand how you'll likely operate one day. 

Create new relationships and continue to build on the existing ones.Now that you're transitioning to sales, I recommend calling warm/hot leads daily - FSBO, Expired, and buyer leads.Fsbos can be found on ZillowExpired on RedX and other platformsBuyer leads can be found at: open houses; Zillow/Realtor,Trulia; Running targeted FB ads; OR partnering with a trusted lender to supply in-house leads or sponsor some of your online ad spend.Book suggestionsI'd recommend:EVERY BP book -https://www.biggerpockets.com/storeMillionaire Real Estate investor AND Millionaire Real Estate Agent by Gary Keller - very practical books.

Laurie Alexander, Keller Williams Agent

I've narrowed it down to 3: Berkshire Hathaway, Keller Williams, Signature Real Estate (This last one is only in Las Vegas and here, they are fee based but also offer great training for newbies)With my intensions of focusing on luxury homes, I worry about working with a smaller brokerage (Signature).

Books on biz and real estate that I have really like:The Book on Managing Rental Properties - BiggerPocketsABCs of Real Estate InvestingStart With Why - Simon SinekTax Free Wealth - Tom WheelrightThe E-Myth - Michael GerberCurrently reading: Extreme Ownership - Jocko WillinkOn Deck: Gary Keller's The One ThingThe 7 Habits of Highly Effective People - CoveyDon't recommend: The Oz Principle.

Make a list of EVERYONE you know and call them. i.e. family, friends, neighbors, colleagues, former classmates/co-workers, etc.Book recommendations:Millionaire Real Estate Agent by Gary Keller - very practical book.

The Millionaire Real Estate Investor by Gary Keller is great, in addition to the other resources already recommended. 

I work for a small town, small time brokerage and he works for Keller Williams in Milwaukee.
