We should never be afraid to spend our money for anything which will benefit us. There is plenty of money in the world and there is no reason why we should not relate with whatever amount we may want. When we do not it is because we have used our concentration and will power wrongly and not because there is any lack in the supply of money. When we try to get the best of anyone in any deal we are only beating ourself by using our concentration and will power wrongly.
