great effort and hard work
বিশাল পরিশ্রম এবং কঠোর কাজ
"Building this company took a lot of blood, sweat, and tears."
"এই কোম্পানি গড়তে অনেক পরিশ্রম করতে হয়েছে।"
To not take something too seriously or literally
to focus and work hard for a long time
to learn and grow from failure
to refuse to give up or change your position
not paying attention; lost in thought
to start over again after a failure
