Flying 8+ hours per day is probably not a good idea for a low-time pilot. Fatiguing, and not good value in terms of experience if all you do is drill a hole in the sky.
AGREED, Combine your hour building with added value. If you don't have an IR or IMC(r) then do that and its a perfect time now to do a night rating. Both will expand your horizons and keep you flying throughout the winter months. The Scottish highlands and islands are wonderful to explore. A short hop across the pond and there is the whole of Europe.
