The advice for a Jew who doesn’t want to lack anything and wants to be attached to Hashem is to accustom himself to pray to Hashem for important matters, as well as for trivial things.

Don’t think that you have to be in hisbodidus, all alone, wearing a tallis and tefillin, in order to pray. Wherever you are, even in the marketplace, you can pray to Hashem. And Hashem, Who hears all prayers will certainly answer your tefillos. ~ Rebbe Bunim of Pshischa zt’l
