I am not into numerology, but this is interesting on the number 45http://affinitynumerology.com/number-meanings/number-45-meaning.php
The essence of 45 may be said to be a pragmatic and results-focused 9.
In addition to the number 9 essence, however, 45 contains reliability, patience, focus on building a foundation for the future, and wit.
45 is worldly and sophisticated.
It has a philanthropic focus on humankind. It is generous and benevolent and has a deep concern for humanity. Along that line, 45 supports charities dedicated to the benefit of humankind.
The essence of the number 45 is continually focused on making life better for people, even when it follows a whim for an adventure. 45 is active and hard working.
Along with its focus on promoting an ideal world, the number 45 can interact in meaningful ways — creatively, seriously, playfully, whatever seems most appropriate or acceptable.
