Having a beef with someone is pointless. In our walk-through life, many people may have wronged us in many ways, but we cannot hold onto that toxicity. It is not healthy to hold a grudge or have a long-term beef with anyone. If you want to move forward in your life, you must learn to forgive but not necessarily forget. You will need the cooperation of as many people as possible in your quest for health, wealth, and happiness.
If you come across someone who has done you wrong, you can smile gracefully and carry on without the negative feelings. Moving on without addressing the past does not give them a ticket to do it again, but it shows the maturity and growth in you. Focus on where you need to go and not the past. There is absolutely nothing you can do about the past, but you are entirely responsible for your future.
