Lack of contentment is called greed and it has led many people to their early grave and even some to a state of insanity.
We are humans and we always want more and more but let's be very careful of the driving and motivating force to achieve them.
We all humans have our strength and weakness likewise our source is different and our plans likewise are so different, so we should understand that we cant have Everything that belongs to our neighbour, everything has it own price, some we can afford and some we cannot afford.
We should learn to let go of something we cannot afford, and if its a need or a most, we should patiently set it as a goal and do everything moral and good to get it.
Lack of contentment, make people to go extra miles even at the detriment of others peace and sometimes even life.
Be contented.
No matter how small it is, be okay with it
More will come when you conquer greed
