The system we are involved in is devouring people´s dreams at any moment, with corrupt movements in the politics, with another war or rumor of war, what about social pressure to look like "you should" be to be ok. All of this is crap.
You deserve to dream more than what the society tells you to be or to become in, a typical life to work full time schedule, have debts for pay what you adquire and to be enrolled in a system of success is worthless!!
Enjoy simple things: The simple your life, the happier you are. There is no more reward than enjoying small situations like the sunrise in the morning, your pets noise before you go to work or the eyes of your family when they come home.
Never stop being a child: The wisdom come with the years... but the child you have inside has to live each day of your life. Imagine, dream, think about the absurd, because most of the adults are busy thinking some rational ideas.
Gratitude, the diamond in your life: Do you know why humans always want more? it is because they has a deep hole inside that can only be covered by the gratitude. The gratitude will tell you it is enough to your soul, so you wont need more, and you would be satisfied in an awesome way.
The mindset of a happy person it is not focused on what others could see from him/her... but in what he/she really is.
Enjoy.
