Try to keep flying as much as you can afford. If you take a break you will get frustrated. The aim should be to enjoy your training (see the eventual licence as just one milestone along the way) - its all flying after all.
MJ's advice is good only if you are training for a purpose and the goal is to get the licence asap. But since you are flying for fun - well then, fly for fun when you can afford it. The funds for the QXC and so on can build up in the meantime. Yes the QXC will be a bit longer away in terms of elapsed time, but don't let that matter.
Are you confident you will have the resources to keep flying once you have qualified?
