I just wanted to share that I am told that the Shlah Hakodosh wrote in sefer Shnei Luchos Habris that today, the day before Erev Rosh Chodesh Nissan, is an auspicious time to ask for parnassah.  He writes that one should fast today, but if not, the fast could be redeemed through giving tzedaka.  Either way, one can say this tefilah, which asks Hashem for parnassah and that our merits not be used up in this world.

Don’t forget to give tzedaka.
