~first~ and ~second~, your combination is almost made in heaven. "Almost" because you likely have a few sharp angles that need smoothing. Your numbers suggest this relationship is founded more on intellect and inner/spiritual levels than on the sensual, physical plane. 

~second~ is practical, grounded, and goal oriented; they are a doer who can take an idea, quickly eliminate what is unrealistic or unworkable, and bring it to fruition. ~second~ is of the earth. 

~first~, on the other hand, is the seeker: philosophical, intellectual, a bit of a dreamer, and full of ideas. Earth and heaven make up this combination and neither can exist without the other. Although this is only one aspect of the chart, its influence will help you overcome many of the obstacles and challenges inherent in every partnership.

This combination is often found among relationships that started early in life. The numbers are drawn to each other because what each has to offer is exactly what the other needs. ~second~ (the 4) is attracted to ~first~'s more abstract and philosophical outlook on life. It inspires a sense of freedom and space that is lacking in their own solid, dependable, but sometimes too structured and restrictive views. 

~second~ offers ~first~ a stable, secure port in an internal universe that is often chaotic and unstable. With the 7 as ~first~'s number, they understand the dangers that lurk in the corners of the subconscious when the mind wonders too far into the realm of dreams and abstract fears. Where ~second~ offers stability, peace, and comfort, ~first~ brings freedom to ~second~'s more restrictive mental approach. The complimentary traits of the 4 and 7 create romances that can last a lifetime. 

The areas where you may need to compromise are of the more mundane, material type. While ~second~ requires order and respectability (and feels uncomfortable and insecure without it), ~first~ is comfortable with a bit of chaos and is not concerned about the approval of others. If you are successful in accommodating each other in these areas, you should be able to get as close to being "soul mates" as any two people can.
