Teen, before I respond, please allow me to apologize in advance if something in here rubs you the wrong way. I hope that it doesn’t, though. I thought it through carefully and edited it, but I’m not Mr. “Emotional intelligence”- I’m more of an intellectual debater.
Teen, how do you define “good person”? Many liberals believe they are more compassionate that conservatives (and a lot of them are), and will defend men deserving of death from being killed due to compassion. Yet, much of abortion today is straight-up infanticide according to all rational thinking- killing innocent babies who were born already because they inconvenience the mother. This is good? This is murder of the most innocent humans on earth- little babies, while the same people will defend terrorists and murderers. They believe they are good, but clearly something is wrong.
We humans are not machines. We have emotions and desires that corrupt our thinking and prevent rational logical thought. You have already identified the source for your beliefs, one that I completely share with you- laziness, or ADD as you mentioned in another post. When I was in 6th grade, davening mussaf shemona hesrei on Yom Kippur, the thought “who said Hashem really exists?” crept into my head at this time. Throughout, high school, I was always bothered by such questions like “Why did the rabbanan makes our lives so hard? Isn’t the Torah good enough?” and other such questions. I realize now that while I needed to deal with the questions, the source was laziness- it’s easier to be non-frum than frum. Once I dealt with the questions as best I could, it was easier overcoming my nature. I still struggle with it, but it’s part of being human.
Being non-frum is the path of least resistance. However, the Torah says that one who does not do the mitzvos will get punished (2nd paragraph of Krias shma). Once you are a believer, then the 2nd paragraph of shma spells it out. Hashem determines who is a good person, and HE determined that a good person is one who does the Mitzvos. As the first paragraph of mesilas yesharim says, Hashem created the world to bestow kindness upon us. However, this kindness can only be fully achieved in olam haba. The way to earn it is through torah and mitzvos. If you would tell you parents “Why do I need to work? I’ll just sit around and be a good person”, the answer is that without work, you can’t feed your head, and you can’t afford shelter, and you die. So if you want to know why you have to do mitzvos, it’s because there is no such thing as being a good person without them.
That said, Hashem understands everyone’s nature. someone who suffers from innate laziness or ADD has a much harder time getting up for minyan than someone who doesn’t. Someone with ADD will never be the masmid that someone who doesn’t suffer will be. As long as that guy does his best, Hashem has no taanos, even if the “velt” doesn’t understand.
As for your parents’ input into your life, they understand this. When I make sure my kid doesn’t play with fire or doesn’t cross the street on his own, he chafes at these restrictions. Why can’t he determine his own life? The answer is that he doesn’t fully comprehend the consequences of his actions. If I let my kid do what he wants, he will end up really hurting himself. Should I abrogate my responsibilities as parent because it interferes with my child’s lifestyle?
Again, my apologies if any of this didn’t come across in the manner that i meant it to be understood in.
