What do you know now that you wish you knew back when you began your career?

My friend and speaker at my most recent event, John Brubaker, posted this question recently, it really resonated with me. www.coachbru.com 

What do you know now that you wish you knew back when you began your career? 

For me, it was "Be willing to do the hard things!" they don't teach you this anywhere. In our society they teach you to do the easy and comfortable, but that is not a good path to career or financial security: It is an easy way to be being expendable. 

I would be great to hear everyone's comments
