When you have more than you need, build a longer table not a higher fence. Meaning you should share what you have in excess, not hoard it and try to keep others in need from accessing your abundance. Many civilizations in the past have held the view that taking crops or other food items was not stealing as long as the person was hungry and needed to eat. When you have more than you need the right thing to do is to offer your extra resources to others who need it, not build a wall and be selfish.
Life is hard, and people who hoard or who never consider the needs of others make it even harder. Be kind and generous, show the best of humanity and not the worst. The feeling of satisfaction that you will get knowing you made a difference in the life of someone else is worth more than having too much and not sharing. Life is short, and generosity and kindness are gifts that always come back to benefit you later on. Build a longer table and invite others in to share in your bounty, don't try to hold onto what you don't need and the expense of your spirit.
