As long as you are alive, there is a chance for improvement.
যতক্ষণ জীবন আছে, ততক্ষণ আশা আছে।
"Don’t give up—when there’s life, there’s hope."
"হাল ছেড়ো না—জীবন থাকলে আশা থাকে।"
it is a waste not to use your mental abilities
a sudden and brilliant idea
To continue practicing a custom so that it is not forgotten
to keep persevering and not give up
to suddenly stop communicating with someone online
Things are more fun or effective with more people involved.
