The pressure we feel to find a perfect job is too much, and we are so multifeceted that we can't love only one thing. The meaning of a job is to belong to a group of people, to get involved into a certain task, and to earn for living."
This article was quite interesting though there are some extreme opinions. We should take it for granted that there's no ideal job. And your interests may change as you get older. If so, nonetheless, we can be easily lost wondering what to do, what to choose. Career is important, indeed, in a sense that you are going to spend most of your life on doing it. The time you are in the office is longer than time you are with your family. So it totally makes sense if you wish to make a right decision, but it shouldn't be an obsession. Adjustment will be necessary. You'll be successful if you could get used to a new environment, make the most of it and enjoy whatever you are in charge of. Fulfillment is not something that you wait until it comes, but something is there waiting for YOU to find it. Maybe. At least it releases ourselves from the pressure to have an ideal job.
