Can Buddhism help me find my passion? I have been trying to find my passion for last many years, to be honest I do not even know how should I try to find my passion.
Though I have been practicing meditation for last couple of years (not punctually though), but I think meditation doesn't help me find my passion.

If any one have read "POSITIVE PSYCHOLOGY - HAPPIER BY TAL BEN-SHAHAR"
In short the book talks about 4 type of Burger:

1 RATRACE: means those who eats a vegetarian normal burger and suffer for anticipated gain in future, which never happens.

2 NIHILISM: This burger is both bad in taste and not even good for health, means worst living style.

3 HEDONISM: This burger is only tasty but not good enough for health means i like watching videos on YouTube but it doesn't have any future.

4 HAPPINESS: This burger is both tasty and good for health means one loves doing something and also have a bright impact on future.

So everyone want to eat the 4th burger, Can anyone help me find.
The "passion" you talk about sounds like a craving for something which you haven't defined. Your question seems to be asking, "I crave something (I crave something to feel passionate about), but I don't know how to find the object of my craving. Can Buddhism tell me how to find what I crave?"

I think that basic Buddhism teaches one to recognize that "craving" as the source of dissatisfaction.

If your craving were for the sense-pleasure or the feeling-pleasure of an addictive drug (cocaine for example), I think that Buddhism would recommend that you seek less of it rather than seeking more.

The "happiness" you mention at the end sounds to me like it might be Sukha. I think there are several sources of sukha (i.e. several conditions, several types of activity which condition sukha), for example such as listed in the Pali literature section of that Wikipedia article.

Someone once lent me a book, titled The Buddha's Teachings to Laypeople: Practical Advice for Prosperity and Lasting Happiness, which I recommend. It organizes, summarizes, and references suttas which contain practical advice for laypeople. There are a lot of them! It has various chapters: about earning, saving, and spending money; having good relationships with people; making good decisions; and so on.
