If you're looking for extra parnassah in your life, today is an auspicious day for you! This week's parsha, Parashas Beshalach, includes the portion describing how the Jewish people received the manna from heaven for the first time. That maan, bread from heaven, was their livelihood, the Jewish people's ability to survive the desert. There is a custom to recite this chapter on the Tuesday of that parsha as a way of requesting your own increased livelihood. That day happens to be today. The publisher Artscroll emailed out a link to a PDF interlinear translation of this chapter if you would like to daven this passage in the Hebrew with the translation underneath. However, you can recite the passage just as effectively in any language. In fact, saying it in your native language is probably more effective for increasing your bitachon (trust in Hashem) that Hashem will provide you with what you need.
Supposedly, there is a lesser-followed custom that people in need of parnassa will recite this chapter every day (presumably until the parnassa comes along). A more common custom for daily (or as-needed) use is that there is an optional passage in the thrice-daily Amidah (Shemoneh Esrei) that you can daven. The passage should be off to the side or bottom of the page. Artscroll siddurim put it in a gray box like the holiday insertions. The prayer for livelihood is inserted in the section of the Amidah for the acceptance of our prayers. There will be a mark that will tell you where to insert the prayer at the bottom of the page. As with the chapter, you can say the prayer for livelihood in either Hebrew or your language of choice, even if you normally daven the rest of the Amidah in Hebrew.
"Cast your burden upon Hashem and He will support you."
