Before I became a parent, I read a lot of crap about Quality time vs. Quantity time.
The idea was that if you can be around the kids for one intense interactive hour, you can pretty much be absent for the other 23 hours and still be considered super-dad (faster than a speeding bullet, able to leap tall....oh well you know the drill)
Turns out this is absolute drivel.
For while you still might get in only one really good hour with your kids in a day, the trick is that they will decide the hour !
And so, to earn their interest (that's right, they're not interested just because you are their parent), their confidence, and their friendship, you need to be available to them for long stretches of time.
As always seems to be the case in life, there really is no shortcut to success. Anything worthwhile takes time, patience, and perseverance.
