Proverbs 19:4 KJV — Wealth maketh many friends; but the poor is separated from his neighbour.
Wealth. Substance. Sufficiency. Gifts. Generosity.
Your friendships are based on some form of value that is attractive.
If you want to make friends, first identify your inherent wealth.
And in that, see friendship as an opportunity for you to share what you have with those who have the capacity to value you.
