We pray to the one true God, the most Holy Trinity.
But we also know that we can speak to the other persons in Heaven, deceased relative/friends/priests, Saints, holy Angels. Seeking help from particular persons in Heaven, to pray with you for some intention, can be very effective.
Today I’d like to recommend seeking help from Saint Joseph, in this year of St. Joseph. There are many different prayers you can use, including speaking your own words, without a formal prayer. I would also recommend trying this one: Prayer of Praise to Saint Joseph.
Blessed Carlo Acutis is a good intercessor, esp. for certain types of requests. He was 15 when he died. See this Novena to him
It is also helpful to pray for the souls in Purgatory, such as persons you know who died at some time, as well as those who have no one to pray for them.
