Afraid to take the next step, how do I get over the hump?

[Allen Mock]

I started out like most others on this forum by reading books and taking small steps towards my goals. I bought a duplex about three years ago, but because of family obligations and work it sat for a couple of years. The building I bought had a previous  absentee landlord and as a result the building had much delayed maintenance, damaged floors and burst pipes. The basement had flooded damaging the two furnaces and water heater requiring new. I have much experience in construction and hvac and repaired and replaced everything myself. It was a very long road.  The build took a lot of time and perseverance to get it back into rental condition.   Now the building is completely rented and cash flowing nicely. I love having the extra money coming in and see the benefits of owning rentals but am now having a mental mind block to take the next unknown step to the next project. I thought after the first one it would get easier.   How do I get over this? Anyone else run into this? Thanks guys/gals
