This aspect of the chart reveals a combination that can be as solid as a rock for a long period only to crash and burn in an instant. Stubborn, highly motivated, a self-starter and an unconventional individualist, ~first~ is adventurous and ready to try anything new, even risky endeavors. Strongly driven, people with the number 1 are not usually concerned about other's expectations. ~first~ generally does whatever they want and will fight almost anyone who gets in the way. ~second~ is no less gifted in the areas of persistence and ambition but has a very different attitude and approach. ~second~ is influenced by the number 4 which is sturdy, reliable, patient, responsible, conventional, detail-oriented, and "does things the right way". This difference is precisely where potential pitfalls lie in your relationship. 

~second~ has both feet planted firmly on the ground. Undeterred by the prospect of dealing with things that are boring or routine, ~second~ will complete the job no matter what. ~first~, on the other hand, does not have that kind of patience; they will barge ahead unconcerned about the consequences 

Your relationship can thrive unless ~first~ starts down a path of unknowns with risky, questionable aims. This is likely to happen at times, at which point ~second~ will likely be a stick in the mud and a source of frustration for ~first~. If this conflict is not handled with care, it could bring an end to the relationship. 

However, if ~first~ can respect ~second~'s need for a secure, perhaps even predictable, lifestyle, and ~second~ can understand ~first~'s need to try new things and occasionally venture into the unknown, the relationship should endure. Recognizing and respecting your differences is key.
