All the friends I had left me, with only a few remaining. That's when I realized that I could do better.
This is the lesson, trust no one and don't put any hope to anyone including your best friend or girlfriend/boyfriend.
I think I don't have to give any advice because it's full of motivation and use your common sense, but if you're want to get rich you must get a better job, spend less and always try to become productive by learn a new thing especially a skill that could help you to get a high paying job.
Never spend money because of someone.
I agree with what you stated since there are some individuals who believe that having money will never run out and that you can be free from friends who aren't actually your friends but are only there to support you because they know you have a lot of money, but they also don't know that when you lose money. The unfortunate truth is that.
We have to avoid making the same mistakes we have in the past by learning from them. Prioritizing what is best for our families or ourselves and what will help us for the rest of our life is something we must learn to do. And live a strategic life at all times.
