Hi. The best pieces career advice I've heard of are:
1. Know your strengths and play them. As Marcus Buckingham highlighted, today's society places too much emphasis on having everybody fix and focus on their weaknesses, trying to make everybody perform according to a uniform standard. What needs to be done is for schools and human resources to start capitalizing on people's differences--the unique talents and strengths they can bring to the table--instead of managing and training them to all be the same way. He further highlights that every person's greatest potential lies at his/her greatest areas of strength, so that's what he/she needs to focus on improving to achieve excellence and true fulfillment.
2. Go for your passion. For this I quote Frederick Buechner: "The kind of work God usually calls you to is the kind of work that you need most to do and the world most needs to have done...The place God calls you to is the place where your deep gladness and the world's deep hunger meet."
I've struggled with my first career (I'm a nurse by profession), but now I've quit my job as a staff nurse and am currently looking to transition to another career where I believe I'd be a better fit. I myself have written a lot of posts regarding this process I am undergoing, mainly to help me understand myself better and clarify my thoughts.
