Bitterness often is caused by the feeling of imprisonment in life. The feeling of inadequacy or unjustness often triggers bitterness. A man who is in fact, a real painter or poet, would feel like imprisoned if he has to do ‘nine to six job’ to make a living. There are ghosts of the original self in us, and the bitterness we feel is just a projection of that original self. To overcome such bitterness, you can either change yourself completely as per your surroundings or upgrade your surroundings with your own unique ideas. You can be either your original self or the duplicated version for the society. Both cure bitterness of existence. Read these bitterness quotes to wise you up on the subject.
