You have to ally doing something you genuinely enjoy with something the market is demanding. You can't do only what you like if it doesn't add value to other people's lives. And in order to find the answer for that question you have to be creative and intuitive.

Maybe, until you find the answer for your question, you will have to work on another fields which you don't consider to be ideal or desirable ones, but that is part of the process until reaching to the destiny you aim.

We shouldn't be so delusional about our goals, at same time we shouldn't kill the fantasy inside ourselves. The problem nowadays is that the young generation is delusional, meaning they just want to do what they enjoy, while thinking it's the society's responsability to supply them on their needs for free, without any counter responsabilities and dedication.
