Failing to plan equates to planning to fail. Knowing the difference between happiness and pleasure will help us plan accordingly, as to which one is missing in our lives and which deserves more attention.
At times, we envy the life of others since they have more pleasure in their life, while in fact, that doesn't represent their level of happiness. 
While pleasure can increase your level of happiness over time, if obtained wrongly it can ruin your level of happiness as well.
It's important to choose the words in which we use correctly, eg. if you are frustrated do not say "I am angry", and if you are having fun it is different than being happy.
Are your friends the ones who add pleasure or happiness to your life, party friends or friends in need? and what kind of a friend are you?
Treating yourself with stuff or food can have a negative long term effect while helping others can be cumbersome at the beginning but rewarding for a long term.

Q: What do you do for pleasure and does it help or ruin your level of happiness?
