I sort of feel like a psychiatrist for asking this, but why did you decide to get a PPL in the first place? Is it because you think it is an easy way to make a good living? It isn't. Are you feeling too nervous to enjoy the flight instruction, but when at home you study for long periods of time, you have a strong interest in aviation in general, and you read or inform yourself about a plethora of aviation topics.

If aviation isn't your interest, then do yourself a favor, and stop right now, it isn't for every one and enduring the path to the airlines is only for the hardy of spirit, those who get in for the money are miserable.
