Bhagavad Gita, stoicism, and Buddha say the same thing: Live in the moment and don’t worry about the result. Give the best of what you have in it. I have lived by it.
I know many people who waste life dwelling through astrology, sun signs, moon signs, birth charts, numerology, and other various Eastern beliefs. Instead of doing real hard work, they waste time blaming their fate & life.
Be wary of such people. They will do everything to trap you with their dogmas. They are like viruses.
Focus on Dharam and Karm, and leave rest to the almighty.
