You can still daven to change things. There are some things where I ask “Hashem do whats best” -which school to find, whether x friendship should end or not, I we move or not, and so on.
But plenty of things you should be asking for whatever you want! Hashem wants your prayers, he wants to hear you suffering and asking for change, and second chance, that you need a yeshua.
Besides for asking for a yeshuah or a miracle There are so many things in your hands. If you scream at your kids/children today, if you have koach today, and so on. Definetly daven that you do do well.
Plus you can ask hashem for small things not in our hands. To find your daughter’s shoes with out a hassle, find a new coat for your son in the first few storews you look, amd so on.
You have to balance it out.
