Bhai jaan duniya ki kal kabhi nahi aati but aap ki "today" nahi a k de rahi

"Ab to ghabra k ye kehte hain k marr jaen ge
Marr k bhi chain na aya to kidhar jaen ge"
Brother in this short life, one won't get perfect things, one should enjoy whatever he has, otherwise our life would only revolve around ifs and buts...!
