learning the hard way....
Stick with it!
I sympathize. I work a lot of weekends, my wife works and I've got rug-rats as well. Between the 3 "W"s ...Work, Weather, Wife (ie family comitments)..., I am lucky to get 1 weekend out of three or four to fly. This time of year is especially frustrating as the weather can be ugly for quite a stretch... and of course it's always ugly when you have a free weekend! (haven't flown in about 6 weeks now....)Even if you can't fly because of the kids, you can always go up to the field with them (just remember to keep them safe!) and enjoy the conversation. You can learn a lot just by watching!
We've all reached plateaus (plateaux?) and not seemed to get any better at it and then all of a sudden, you make that first "greaser" landing or go a whole flight without the instructor yelling"I've got it". We've all spent the first flight after a month or two off relearning what we've forgotten since last time.
Stick with it!
