The meaning of Work hard and try hard-Persistent work hard and never give up. Consistency is a key to success by the way! If you work hard surely one-day success will knock you right! But if you fail you will get valuable “experience” experience is man makes perfect and if know one thing Thomas Edison failed 10000 times before he invented the bulb. Some press reporter asked him you will fail 10000 times before invention? And he replied No! I’m not failed I found 10000 times how not to invent the bulb. Your success is also ahead but never ever give up.

here's a quote I saw the other day

“Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent.”
