Those who mean and do good only for others would never reach miserable situations in life.

I can only quote what the blessed Lord Krishna told Arjuna in Bhagavat gita.

न हि कल्याणकृत् कश्चित् दुर्गतिं तात गच्छति

na hi kalyaana krut kaschit durgatim tata gacchati..

Dearest Arjuna ,Those who mean and do good only for others would never reach miserable situations in life.

God has promised that.

.And sure He will keep it
