You only have twenty-four hours in a day. So you won't be able to fit in all the things you could do, and likewise you will struggle to spend time with everyone equally. Think hard about the value of some of the relationships you have relative to the amount of benefit you get from them and how you feel as a result of being around those people. Some will be friends, others relatives or work contacts.
Try to be a little more selective about how you give out the time in your calendar if you are only going to be more worn down as a result of having done so. As with the phrase "less is more" when it is applied to meaning that a bit of quality is better than a lot of mediocre items, I think often that the same phrase can be applied to your own appointment diary.
Let your mobile go to voicemail now and again. After all the reason you have that facility is so you don't have to answer the phone yourself every time! Let people know that you have time out for yourself now and again, or that you are with your family and will not be taking calls, or that you are visiting some friends and will get back to them when it suits you to do so.
Put your family first and ensure that there is some regular time each week when you get together, and create something special.
I recall how as a child, my parents always took me to the cinema on a Saturday morning or how we would often go out early on a Sunday morning to walk in the country park or along the riverbank. The memories of those film shows and my familiarity with the footpaths and lanes that I still visit regularly in my adult life have their roots in those familiar traditions which were deliberately created by our parents.
What was important to you as a child, as a teenager and as a young adult?
The chances are that your own feelings and memories of belonging or of having an adult be interested in your well-being is just as important to your own children. Take time to do the same for yours.
We all appreciate the way that someone clears their schedule to give us their time and attention, so if this is true from our own perspective, what must it be like to be able to give that time and energy to someone who will enjoy having you and holding your attention.
