Passion

What are the things we need to do with passion around us?

Love to our family? Our own interest? Our careers?

What is the difference for a person to do something with or without passion?

It must be huge, but I would say the following might be some of the majorities.

Enjoyment: If you got the passion on something you are engaged with, you will enjoy doing it.
Creativity: You got the passion, you then will find ways to solve problems when you are facing difficulties. You will definatly use your brain more.
Affection: You will be able to affect other people's opinion on this matter. You would like to and try your best to let others agree you and help you to achieve this goal, the one in your heart.
Awareness: You may show less awareness to anything else, when you show much passion to the big job you are engaged in.
Result: Quite obvious, it will return you more since you have the passion to devote yourself into something.
Return: When you have the passion on doing a certain thing, it is not necessary for you to require a return for your hard work, or metally, you don't care for the return. In other words, that is not your motivation for pursuing it.

Love something or someone with true passion, it/they will love you back, sooner or later.
