To be or not to be... a programmer. =)

Hi everyone! I'm 26 y.o. I've worked as a chef at a cafe about 3 years. And some time ago I've started feeling that it is not my calling. In the past, I had worked in many different places, and tried my hand at different professions. Now I have found a new passion. It's programming. There are many things which I should study before I become a good specialist. But I am afraid that it will be boring for me, when I will become a professional.

Calling has a dual meaning. The one applicable in this situations means "a strong urge toward a particular way of life or career; a vocation" source google. 

try your hand at something means to try doing something for the first time. (i.e. I might try my hand at a bit of Indian cooking.) source http://idioms.thefreedictionary.com/try+hand+at

When there are new new requirements, code may change. API's change, features become deprecated. From what I understand, coding is challenging and requires attention and thoroughness. Good job on the post!
