With the way our world is going people just have to having a positive view To Life by themselves because many people are going through a lot and the earlier the better you realize that you are on your own on this planet Earth the better. My point is that in our contemporary world, it is considered that your fate is in your hands, hence it is left for you to do with it as you please.
Having a positive view of life is one that should come from the innermost part of your heart. The world is hard generally for everyone both the rich and the poor in essence people should find that innermost desire to pursue happiness and joy and bring about positivity to themselves and the people around them. No one is depending on anyone again to have a positive mindset of life. In fact with the way we live if you do not add value to someone else's life you would definitely not be adding value to yours.
From my personal point of view, the great way that people can have a positive mindset of life is still focus on aspects that are right in their life and not what is missing. Again we should also understand that positivity can come from even the smallest things. Some of those things includes having someone to talk to you when things are hard, eating healthy and maintaining a balance diet, exercising and so many more.
I have a colleague in my place of work that whenever he comes to work the first thing he says is "I am tired", "I couldn't sleep", this and that every blessed day. He would also make statements like "you should Pity Me" , "nobody can go through what he is going through" and so on. It got so bad that I tried to avoid him every morning because I see that he exudes a kind of energy that diminishes my positivity.
In conclusion, all I am trying to say is that the kind of people you surround yourself with no matter how small or big can affect the kind of energy you have and it could be positive or negative.
This is my participation in the
