All the directions of development

As humans we have quite a few sides to work on in order to succeed in life. For a child, everything needs to grow: emotional health, mental development, physical coordination and agility to list just the major ones.

I personally never know what ball to catch first. Physical activity leads to emotional health, which in turn leads to better mental development, so it seems logical to keep them active most of the time. Yet I feel they need their breaks.

Too much walks, parks, runs and soccer and they get agitated, cranky and want me to hold them. That's when I know I've overdone it.
Home activities tend to be more soothing and mentally challenging, but it makes them want to speed up a little.

Just like with adults, you strive for a balance between running around, growing in all directions and finding a peace within, and there seems to always be too much in each plate to eat at once. And the time you break it into doesn't seem to be equivalent either: 15 min in the morning is longer than an hour in the evening.

At the end of the day, if I am not sure that my own scale is balanced, how do I know if I balanced theirs?
