To me, it was finding my first clients.
I just moved to a new city, and didn't know anybody.
I went to every seminar, related and unrelated to real estate, and just started speaking to people.
In one setting, I found my first listing - a short sale.
Knowing that I was working on this short sale, another person, that I met at a different seminar, referred me to someone who needed a short sale. He referred his friend...
It took a long time (short sales take long long time), and I had to survive, so did rentals, and any type of transaction that I could get...So, making money the first couple of years could be easier for you, if you had some funds saved up for online advertising. You'll never be bored in this great profession though - the market changes all the time, the inventory size, the pricing, the types of transactions...
Best of luck,
Beachfront Realty, Inc.
