If there is any way at all of completeing that PPL, mb, - do it! With the right group, and depending what sort of flying you want to do, post-PPL flying
can be a lot cheaper than flying training - with some experience under your belt it can even be free!
It's very easy to justify giving up, and maybe you should. But I'd advise that, if it's
at all possible, then live your dream. It'll be worth it.
