Which planetery position is responsible for my ambitious nature?

The Sun in Taurus squaring the Aquarius moon creates a tension which makes you want to review and perfect everything and gain a good long term outcome from projects. The Saturn in Cancer makes you take family life very seriously, and you probably want to be the bread earner and provide for your family. You look for a stable financial platform. Taurus is the most earthy of the earth signs and is sympathetic to the Cancer Saturn, and the Virgo Pluto which also helps in this mix.
