How can I work smarter instead of harder?

1. Delegate (if possible) lower level tasks (ie. tasks other people can do with a small dose of instruction and follow-up).
2. Also, FOCUS on the most important things you can be doing in your role.
3. Say NO to distractions or things that keep you from focusing on your most important tasks.

Also, if you find yourself working long hours, nights and weekends, revisit numbers 1–3 above.
