New moon is the time when the Sun and the Moon comes together. Traditionally, the Sun is yang, representing male or fatherly energy; and the Moon is ying, representing female and motherly energy. When male and female come together, new life can be born and that's why new moon is related to new beginnings and creation. And that's also the reason why astrologers encourages people to make wishes in New Moon.
This month our new moon happens on 15 May 2018 on 25 degree of Taurus. Taurus is ruled by Venus, which is related to love and money. I think Taurus is more on money and individual resources, whereas Libra (another sign ruled by Venus) is more on love. So this month, please relate your wishes to material things, e.g. money, income or health issues. Taurus is also an earth sign, earth is grounded, stable, the more practical the better. So this time please organize your wishes, make it practical, controllable and organized.
I believe this new moon is very positive, because most of the aspects for this new moon are positive. First is a trine with Mars and Pluto, representing will power and persistence respectively. Together that most of the planets are on earth elements, including Mercury, Mars, Saturn, Uranus and Pluto (of course the Sun and the Moon are also in Earth Sign - Taurus). Earth element means sustainable, though also means it will take a long time to make things work, but if you can make use of the energy from Mars and Pluto, I'm sure it is only a matter of time for you to succeed. The only bad aspect here is an opposition with Jupiter, but since Jupiter is the great benefic, I would say this is not really an issue.
