Be open to helping others when they don’t ask for it, especially when you don’t have to. Character is what you do when no one is looking. This is not something you will include in your review or talk about to others, but it will help support others. And you never know when you will need help yourself. For sure you will, you just won’t know when and from whom. So why not be there for others? There are so many ways to lend a hand, an ear, your time etc. and if you do, it is much more likely that there will be colleagues ready to extend a helping hand to you when you need it.
