You need to treat your weekends during search just like when you work. Have some fun, work on your project list, or enjoy time with friends or family (for ideas for family, see the link to the book “The Family Book – Amazing Things to do Together” on the Candidates Resource page).
Do what you need to get ready for interviews and networking meetings, but otherwise, take a break on the weekend.
The main issue is that it’s tough to make progress on the weekend. As generally there is no one on the other end of the line of e-mails, voicemails, etc. So as you work by yourself on a weekend, especially after a slow or disappointing week, you tend to focus on items that just don’t move you ahead and miss time to refresh your mind. Rewriting a couple sentences in your resume for the third time are not going to make the difference – being ready to present a positive and confident persona on Monday will.
If you have a burning desire to launch off a bunch of e-mail requests, wait until Sunday night. I found that’s when folks look at their Blackberries/E-mail and tend to respond.
