My friend has been learning to fly for one and half a year. Unfortunately, he gave up the hobby after many crashes. He can take off an airplane, but only rarely does he land it in one piece. Besides that, his wife complaints about the amount of money he spends on this hobby (thousand $$). So, the lesson we learn from this hobby is that one or two mistakes cost money and time. If money is not the issue, just think about the time you spend on repair after crash. Your instructor's advice is very valuable. After each flying session, he points out your weaknesses and strengths. Know your past mistakes so that you will not repeat them again. Make sure that you spend more time on flying than on talking about politics every time you go to the field. Your flying skills are very crucial. The more you practice, the easier is going to be.
