The biggest problem faced by humanity in this modern world is the problem of Worrying.
I personally believe most of us are all programmed to fear and worry, Beginning from childhood where parents and teachers try to teach student by fear and not by love in most of the time,
We can note from the biography of Abdul Kalam that his parents always preached love and he had upbringing with people of positive mind, We can see the result of all that, He was programmed for greatness, and today we all love him and dearly miss him.
So the key lies in overcoming worry and fears by replacing their source with a source of positivity and happiness, Question arises, How ? Or what approach is required for that?
Let me illustrate this with an example, Lot of people are fed up with their company, They don't like the people they go out with, And they fear refusing their colleagues, The solution to this problem is to sit down and analyze all your companions, and deciding which are the ones that are having positive impact on you, and the one you want to avoid, Once you are done with it, Just get away from the negative ones, You don't have to be blunt, and tell them that you don't like their company, You can do it with a simpler and more cordial manner, Also remember to have compassion for everyone, Hence recognizing the fact that the person you think is wrong, probably himself is facing lot of challenges in life, and the fact that no one becomes or likes to be a sadist in this world.
So If one can work on each situation this way by simply following the principle of replacing and not killing, you can make your path easier and better, As you don't have to worry about eliminating something from life, you just need to find something that you can replace it with,
Similarly if you have a bad habit of wasting time of TV watching useless shows, You could look to watch some good youtube Channel where you can gain some good info,
If you think your mind wanders too much and fear keeps coming to you, You can just listen to some good motivational songs and reaffirm positive thoughts, Hence replacing negative with positive.
To Sum it up, Don't try to kill something from your life, As that's not a great way to overcome negatives in life. Instead look to replace them with something beneficial and positive,
Make progress everyday, and soon you will have no time for Worries and fear, No time to watch fruitless TV serials, You will end up living a life where you would get benefits for things that you enjoy.
