Knowing that HN is generally against it, I say it anyway: I recommend religion and religious teachings which address this and many other daily worldly issues perfectly. Christianity and Judaism both have excellent resources. Religious scholars have actually been the best psychologists but are generally dismissed by non-believers.
Edit: for those asking for specific recommendations. It’s always best to find your own path according to the religion of your parents and environment. However, I can suggest that you investigate Mussar and look up some books in English.
“Musar is a path of contemplative practices and exercises that have evolved over the past thousand years to help an individual soul to pinpoint and then to break through the barriers that surround and obstruct the flow of inner light in our lives. Musar is a treasury of techniques and understandings that offers immensely valuable guidance for the journey of our lives.... The goal of Musar practice is to release the light of holiness that lives within the soul. The roots of all of our thoughts and actions can be traced to the depths of the soul, beyond the reach of the light of consciousness, and so the methods Musar provides include meditations, guided contemplations, exercises and chants that are all intended to penetrate down to the darkness of the subconscious, to bring about change right at the root of our nature.“
