Surrounding yourself with energys similar to yours like people who share similar interests and talents rather than the opposite will allow you to grow in some many ways it's not about rather they are blood related or anything among the shorts even if they are it's better to be with peace than rage and discomfort grow your seed in rich mud and it will form a very beautiful tree....
However if you're surrounded with negativity and negative energy it's good to try your best to stay away from them even if you live together... don't ruin your growth for poor mud to plant your tree on instead wait and look for rich mud until you have found it.....
