Lawyers are busy folks! Sometimes, they feel swamped, and they always feel overworked. They just don't know where they will find another billable hour in the day.
Seriously, lawyers do suffer from stress, often solely related to the management of time. One report shows lawyers suffer depression at twice the rate of the general population. Much of this has to do with anxiety over key legal issues or with the confrontational nature of some legal fields. But, just as exercise and diet can help relieve these stresses, so can better Time Management.
Lawyers starting with big firms have advantages. They are supported by trained staff, and much of their work process is managed by proprietary software applications. Still, they might bring baggage to their office that presents itself as a time pressure.
Lawyers building their own practice lose cases and money because of poor time management - and many never see the connection. In their minds, they are in the law business, and make the procedure and organizational issues back-burner stuff.
Finally, do not spend too much time on time management. Do not let it define the job. Assess your problems as a whole. If you don't have the staff support, see what you can sub-contract to a paralegal, bookkeeper, or a virtual assistant. In your first days, put teeth in your bite. Chew up the most odious duties first thing in the day and complete them on a "false" deadline until the action becomes second nature.
Time is a law. It is relative. And, it is not manageable. However, you can manage yourself. Start work there!
