As a student pilot with 50hrs I can tell you it's the best thing you'll ever do apart from having kids!! I love it!
In saying that I dicked around a fair bit (I was more obsessed with purely just being in the air than learning to progress) before I realised that if you knuckle down and learn procedures etc.. By heart ASAP then things will move along more rapidly. Nail the theory quickly too.
Most importantly as has been stated, have fun!! I have a great bunch of instructors at a small school & regional airport so I'm lucky in that sense.
