Do you have a 'heads-up' habit?

One habit that has served me well for many years is the 'heads-up' habit. It's really simple. Every week, I pause and look ahead, as follows:

• Every Saturday morning—before breakfast—I look ahead at least four weeks. The motivation is to identify big tasks (typically international trips and major events) loaded into my diary: the objective being to make sure sufficient preparation time is allocated to think, write speeches, build slide decks or prepare well. It gets me thinking—early—about the main points of scheduled talks or important meetings. It has the added benefit of highlighting gaps in trip schedules and, therefore, opportunities to request additional meetings or activities well in advance. I also check trip logistics, especially travel time, accommodation and transport. There's nothing worse than realising at the last minute that an important connection or hotel booking has not been made! This part of the heads-up habit helps me avoid last minute rushes.
• Every Sunday evening—after dinner—I look ahead seven days. I do this with my wife. We walk through our respective calendars to see what activities we need to plan for, and whether either of us will be home late from a commitment or away overnight (a seemingly simple but incredibly important thing, especially when it comes to planning the evening meal!). This part of the habit helps me manage important relationships.

In the past, I sometimes lost sight of important upcoming activities (and ended up suffering late into the night trying to make up—the results of which were never that great). However, last-minute rushes have become a rarity since I embraced the heads-up habit. If you don't have a habit to stay of top of your commitments, you might like to try this one. It made my life easier and I seem to be more productive. Also, my wife says that I'm easier to live with!

Most people I know live fairly busy lives. Western culture and the 'always on' society we live in has done that to us. However, some—by my assessment anyway—have become a bit too busy for their own good. Societal norms seem to reward busyness and excellence, yet cracks start to appear when we get very busy for long periods. We get tired and make mistakes. Our commitment to do things with excellence suffers. How do you cope in such situations? Do you plan well ahead; or, do you manage your commitments on a daily basis; or, do you simply back yourself to keep up with what work and life serves up?
