Its a trap.
Everything comes with a price.
Doing what you love includes a lot of things that you do not love doing,but you will have to do it, so that at the end of the day you can do what you love.
Example: A middle class man
An ordinary middle class man does not like his job. And almost half of people doing jobs do not like their jobs. Even worst- they just hate their jobs.
Why do they do it then?
Because, doing their job i.e. doing what they do not like affords them basic necessities. It affords them smile on their kids face. It affords sigh of satisfaction and relief on their parents face.
If married- it affords him satisfaction of watching his wife living a comfortable life (if not luxurious).
Do not just believe everything and anything you read over internet and social media platforms. Use your brains to evaluate and analyze.
But the fact is that- when you do something you really love doing, you will better be able to cope up with the things and tasks that you do not like.
On the contrary if you do something that you hate- the probability is that it will be harder for you to cope up with mundane things and tasks- resulting in quitting. Yes, you will quit sooner in the later scenario.
This is why a lot of successful people suggest you to do What You Love. But they do not tell you the price you have to pay in the pursuit of doing What You Love.
