Capricorn + Capricorn
The two will really be able to understand each other, since they both are similar. They will be able to achieve the biggest of goals, because Capricorns are very ambitious, organized and hard-working. One of the problems that might occur is that the relationship might get a little monotonous, since Capricorns focus on everyday routine a little too much and often forget to enjoy life as it is. They also may often find it hard to loosen up and take off their mask of seriousness, and this another risk of unnecessary boredom. The good thing about this match, is that both individuals are very loyal, so commitment is not a problem for them, and in fact it is probably exactly what they want. All in all, this is a pretty good match and requires only a few adjustments to make it work really well.
