Here are a few things that probably nobody told you about what you should be doing at work:

Add positive energy to every interaction
Be authentic
Treat customers beyond expectations
Offer help to others before they ask
Leave things better than you found them
Recognize the work of others
Lead challenging projects
Foster curiosity
Have fun, but never at other people's expense
Reduce costs
Ask why
Change what's not working
Ask what it's for. Ask what's the problem that you are trying to solve
Find how you can use your platform to do the most good
Don't tolerate gossip, criticism, judgment, or cynical asides
Start a community. Start a tribe
Look for opportunities, and find solutions. Ask what you can do
Simplify processes (even if you don't work in operations)
Advocate for others
Help invent a new product or service that people really want
Get more competent at your job through learning every day
Have difficult conversations
Take ownership of your career
Show your work. Just working hard is not enough
Understand what drives different people
Never make assumptions
Figure out interesting problems
Smile

Now more than ever, we need people who want to lead the change. People who want to make a difference and create a positive impact. It is not about titles. It is far beyond your job description. It is never too late to reflect and define how you want to perform.
What would you add to this list?
