Some of life's greatest lessons are most effectively learned through experiencing them. How many times has someone said to you, you should really do X, Y, and Z or don't do X, Y, and Z? For example when I was growing up my family tried to teach me about saving and being careful about what I do with my money and definitely wait on getting a credit card. Did I listen, of course not..lol, and now I'm paying the price, literally. We didn't have much money growing up so I wasn't able to receive an allowance or have any means to practice handling and managing money. I was just always told you should be careful and so on. When I went to college I got a call in my second year and was you know, that half sleep where you still have no clue what's going on. Well it was a credit card company offering me a card and I was kinda like yeah, yeah, yeah. One week later a credit card showed up and instead of being smart and canceling it I said, cool and decided to have fun with it. Well now I'm paying the price for my stupidity of not being able to save. I have my Bachelors in Music education, I've been a successful private trumpet instructor, and I'm halfway through my master's degree in music education. With my degree I am over qualified for any basic job to give me an income until I can get a teaching job and it's just taking me time to build a reputation for teaching. I should be earning around $32,000 a year but because of my debt I can't afford an apartment since I am working day to day. I have to live at home because I have such high credit card debt. If I didn't have that debt I could easily afford an apartment. I'm thankful for learning this lesson at an early age as I will have my credit restored by the time I'm thirty but if I had just listened I would have been in this situation in the first place.
I apologize for the long story but I think it proves my point very well. I bet you could think of someone or even yourself when something like this has happened. The true question though is how you are going to handle it. For me I have definitely learned but there are many people in my same situation who claim bankruptcy and then begin the cycle all over again and don't learn from it. I have learned, will you? I am not just referring to money issues, this could be about anything!!
Another way to see this is when you were in school or someone taught you a Jedi concept and you sorta understood it but once you experienced it you were like, oh, now I get it. So even though we are told hundreds of times about something it might not always be enough until we experience it. So what's the lesson here, listen to people who know what they are talking about. They might seem or sound like they don't know what they are talking about but when someone who you value their opinion tells you something listen to what they have to say so you don't have to worry about experiencing just to find out, I should have listened to them.
