Mental Health America advises:
Set manageable goals each day. Being able to meet priorities helps us feel a sense of accomplishment and control. The latest research shows that the more control we have over our work, the less stressed we get. So be realistic about workloads and deadlines. Make a "to-do" list, and take care of important tasks first and eliminate unessential ones. Ask for help when necessary.
Savvy says: Use web tools to help you manage your time. I like Remember the Milk, a free electronic to-do list. Reminders can even be sent to your Gmail or sent via text and IM. The best thing about it is you can sync it up to a lot of programs including Microsoft Outlook and iCal. For me, the biggest perk is accessing it on my cell phone!
