If you believe financial collapse starts and ends with bad investment, then you need to rethink. Your closest relationships are either building or dismantling your wealth because they involve the wrong people. Your social circle operates as a hidden tax or a compounding asset. Every conversation you have either increases your ability to judge or erodes it. Every friendship is supposed to help you grow or kill your growth. The first person you should avoid in your life is the parasitic friend. The one who is in the relationship for what they can gain. These friends do not contribute to your life; they consume what you have and only come when you have abundance. but disappear when you are in need of them.
Unless it is a business transaction, any type of friendship that only occurs when there is something to gain and requires give and take isn't friendship, it is opportunism disguised as friendship. When your friendship is stealing your emotional energy, attention, and time, then you should run away from it as quickly as you can. When building wealth, time is very important; it is the currency for wealth, and so spending it with people who are not valuable means you are just foolish and not being generous. Every hour spent with a person who doesn't value time is an hour stolen from your future.
This might sound like it's too far, but one person to avoid in your business life is an angry person, one who is emotionally volatile. An angry person cannot handle their finances because they are not emotionally in control. Anger is a decision-making framework where you are left to decide to either react or handle things logically. Being volatile emotionally is a disadvantage, and rage eliminates the ability to be patient, which is needed for a compounding return.
Avoid a person who flatters you in your journey to success because they want to tell you what you want to hear and not what you need to know. Being friends with a flatterer means every step you take is the best; they will not be able to tell you the truth to your face. These people applaud your recklessness and bad decisions. Before I leave, let me say this very simply: learn to set boundaries in all you do, you should be able to say NO to a few decisions that can ruin your success.
