Steve Pavlina has written a great blog on the challenge of choosing the right career. You can read it at http://www.stevepavlina.com/blog/2007/11/the-challenge-of-choosing-the-right-career/.
Whatever career (or non-career) path you take and however ‘good’ or ‘bad’ you find it, it is possible to gain something positive out of it, if you choose to look at life in that way.
When I was a student I took a holiday job working in administration for a high street bank (the sort you and I go to). I quickly knew that this type of organisation would not suit me for a permanent career as it had so many rules and regulations, leaving little opportunity to use initiative. And the level of detail involved was incredible! None of my strengths that I like using were relevant at all.
There is solid evidence (linked to positive psychology) that when you can use your strengths in your work, it is better for all concerned.
So if you’re trying to work out what career to choose, one area I’d strongly recommend you consider looking at is where your strengths lie. When you know this you can then think what types of career might require you to use them.
