Assalam alaikum,
We sometimes forget the importance of the simple yet powerful Du'a or Supplication of ISTIGHFAR-ie the saying/reciting of "ASTAGHFIRULLAH" (I seek forgiveness of Allah). We learn it from our 'Ulama that some of the virtues of ISTIGHFAR are:--

Removal of anxiety and du'as are answered.

Istighfar opens the door of sustenance.

It also opens the door of Mercy and Knowledge.

Reciting Astaghfirullah helps us to calm ourselves and wipes out variety of worldly worries from our mind and body.

Ibn Abbas, may Allah be pleased with him, reported that the Messenger of Allah, may Allah bless and greet him, said:--

"IF ANYONE CONSTANTLY SEEKS PARDON (from Allah), ALLAH WILL APPOINT FOR HIM A WAY OUT
OF EVERY DISTRESS AND A RELIEF FROM EVERY ANXIETY, AND WILL PROVIDE SUSTENANCE FOR
HIM FROM WHERE HE EXPECTS NOT". [Abu Dawud].

We should, therefore, include recital of ISTIGHFAR (at least 100 or more) in our daily Zikr, when we come to Remember Allah.... in the mornings and evenings.
