The biggest skill you can develop is the ability to reset fast. Bad conversation? Move on. Bad day? Start fresh tomorrow. Missed workout? Hit it the next day. Poor decision? Learn and adjust. You can’t control what happens to you, but you control how long you let it affect you.
Best career advice that I can give: Don't ever attach yourself to a person, a place, a company, an organization or a project. Attach yourself to a mission, a calling, a purpose ONLY. That's how you keep your power & your peace. It's worked pretty well for me thus far.
