Beams, low ceiling large river flow from east ...

My living room and dining room have beams going across the ceilings. The ceiling is quite low. My house faces the SE, and has a large river flowing from the East to the West. I have large picture windows opening up to view the river and the hills on the other side. I live on a hillside. The back of the house faces the hillside and is North/North West. There is a long cutout in the front of the house allowing the front door to open in the center of the house the door faces East. My mother lived here for 30 years (house built in 1964), she never accumulated any wealth. I am afraid this will happen to me. (I have a home office here and have just become aware of Feng Shui.) Where and how do I begin? I have limited income, but lots of time. I am a kua 3. Thank you very much for some place to start. Respectfully, Carmen
