look at the beginning for the question: why are you an optimist? why should u see the world that way?
you and nobody elese can chose, how u wanna think.
It is also a point of view, for example you can see to everything bad in the world and think that the world will crush or u can see the good in people and the good in the world.
If you are trying to give people the same happiness, what u are wishing for your self, than automatically u become happier.
It starts how u begin your day.
Are u one of those persons, who just grab after the mobile phone and see what happend in the last few hours on fb, instagramm, etc. .. ?
LEAVE IT -- THOSE `news´ will also be there in the next hours....
- instead of this -
close your eyes and imagine for yourself a good day,
a day, which is realistic beautiful, no matter if it is at work or in the free time.
Imagine, what could make u happy, if you do those things that makes u happy, you will automatically become success in life- because the biggest success in life is happiness.
cheers
