Timothy 6:17; Charge them that are rich in this world, that they be not high-minded, nor trust in uncertain riches, but in the living God, who gives us richly all things to enjoy.
Many live through life with worries of tomorrow only, others live life for others and forget to enjoy the gift they themselves have received from the father. There some who also forget how to live and allow themselves to be distracted by unnecessary things in life.
As much as material things are important in life it is not everything. We can learn to live in happiness and remain joyous everyday every time, it is only a matter of choice and what we choose allow to influence our happiness. If you happiness is based on material things or in this world then you may easily be swayed.
The life we have been given is for us to enjoy and this we can do by appreciating God and keeping our faith firm and strong such that our source of happiness is God and not man. This way we will always find happiness even when none exist.
Remember life is a gift which is why it is called present, and every day you get to see the sun shine do not forget to be grateful.
