Make sure you have fun, it will be hard at times, but often one day it seems you will never get it, then it suddenly clicks
It seems some get all obssesed with how quickly and cheaply you can get your PPL. If your goal is airlines, or having a certificate to put on your wall then never flying again, then ok.
If you're planning to be a bimbler who flys a couple times a month, training once a week may work for you just fine. (I agree a few close together before 1st solo helps). You may take a few extra hours, but it will give you more of a chance to understand what you want to do post PPL and to understand the comittment flying will be, if you continue to do it.
I mean you should actually enjoy the flying whether it is post or pre PPL and you will be spending the money either way.
