Which pictures do you think show an expression of happiness?

Talking about happiness, everyone have their own right to express what happiness means.
For me, happiness means as an expression of pleasure, peace, not anxious, not worry, and whatever they called which can make us to smile..
Yes it's just a simple definition of happiness and I don't wanna get stuck of it..

I agree with the statement "happiness is a choice"..
Happiness will always be a something good until you meet a condition to choose which ways will toward you to a happiness or we can say greater happiness.. this is what i mean of "Dilemma of Happiness"..
I believe that we're all have met that kind of condition.. a condition that could make you turn your head on to considerate which ways are better.. It comes out naturally, when you met condition like you're willing to study abroad which promised a better level of education but in the other hand you have to leave all the people you love so you could not hang out together with them..

What do we have to do if we meet that condition again?
The answer is considering..
Furthermore, you will ask how to considerate?
And the answer is follow your heart..
Yes it works, but just for a simple problem decision that won't give a great effect to you if you choose a wrong way..
So, how if the condition it's so complex and will cause a great effect to your life?
Like, deciding your marriage (do you really love him/her? are you ready to live with him/her in the rest of your life?)
or when you want to decide your career or your major study, etc..
Above are examples that we do have to choose correctly, if we don't want to regret in the future..

"Opportunity Cost" this is an economic theory that I think can help us when we find it difficult to decide.. This theory explains the value of the next best alternative foregone as the result of making a decision, it is referred to the cost of doing the best thing and ignoring the next best thing to be done.. Example, a person who sells diamond for $5,000 denies himself or herself the opportunity to sell the diamond for a higher price in the future, inheriting an opportunity cost equal to future price minus sale price..
Opportunity cost theory is useful when analyzing the cost and benefit of choices and it doesn't have to express in monetary terms.. These are steps to use the theory:
1. Recognizing our interest
2. Deciding possible options
3. Analyzing cost and benefit for each options
4. Comparing cost and benefit between all of the options
5. Choose your way!

So, how about if you meet a condition like this:
"You are studying abroad now and you're separated by the distance with someone that you loved.. Your study program requires you to have an internship for about 6 months and you have your freedom to choose where will you do your internship.. You have a dream to do your internship abroad which you believed it will gain your experience and give your higher value rather than you do it in your origin country and you think it's a rare chance for you.. In the other hand, you can go back home and do your internship there.. So you can be together with your love, family again and etc2.."
What will you gonna do?

Choose your own way!
