The "Best Training" is as relative - significant or insignificant - as what is the best apple pie in the world, or what is the best vacation ever, or what is the best cell phone... You can drive a Mercedes, a Cadillac or a Bentley and still have accidents (the car does not make the driver).
Real estate training is only an educatin. It will not make you a successful real estate agent unless you believe in your heart that you will be good at it, that you will believe in its core, that you will dedicate150% of yourself without even thinking about it towards succeeding. Selling real estate is more than a job, it's a calling; it's something you need to breathe in and out each day, to swallow the deceptions and to embrace the next lead and, at the end of the day, feel good about yourself and look forward to do it all over again tomorrow.
Show initiative (your own willing desire to learn on your own): If you lookl closely at all the big or samll name brokerages, you will notice that in each office of each franchise, or not, there is always one star shining brighter than the rest, and thereis a handful of others that are a few lumens below the star and you have a bunch of dim ones. Also notice that the stars have been with the same broker for years. So, pick any broker and take advantage of every training they offer but HERE IS WHAT I THINK IS THE MOST IMPORTANT: Observe and learn from the brightest stars, how they do things and even ask them why they do it (most stars are usually willing to share their knowledge among their peers); or, find a star and askhim/her if they wouldn't mind if you were to go out with them on listings or showings now and again (the worse thing is they can say "No." but there will be one or two that will be gald to saa yes); or, whenever you go out on your own showing properties to meet other agents, pay attention on how they are handling themselves with their customers or if they are the listing agents who will show the house and you bring your customers, study how they show the property.
Other venue. Even if you chose Keller Williams but the broker isn't there, so what? Your local real estate board should offer tons of free enlighting and resourcefull classes on just about everything agents need to help keep you on top of your game. By-the-way, most local real estate boards offer bunches of those free invaluable classes that give agents 3 hours credit towards your 14 hour Continuing Education (I ma not sure, though, how many continuing-ed hours are required in California). That is how I do my 14 hours spread in two years.
Research has proven many times that people who take a hobby spend more time per week and more heart dedication (not considering the pocket money that goes into those hobbies) than they put in their own work or profession. I am a RE/MAX agent and real estate is my hobby.
So, Marie, start searching in your soul first, make real estate your hobby, then look for a broker.
