no it’s not. but you should know what you’re getting into.

in the beginning of my PhD i really loved what i was doing. from an intellectually point of view i still do. but later, i.e. after 3 years doing a shitty postdoc, i realized that I was not cut out for academia but nevertheless loved doing science.

however, i was lucky to find a place in industry doing what i like.

so i guess my 2c is: think about what comes after the PhD and work towards that goal. a PhD is usually not a goal in itself. hth
