Spend your love unconditionally. It will return to you tenfold. ~~~Anonymous
The imperitive word in that sentence is 'unconditionally'.
So often advice, proverbs, sayings all suggest similar ideas: 'Do unto others...' 'Love thy brother as thyself...' 'Pay it forward...' 'You reap what you sow...'
All great ideas, all good advice...as long as you remember to 'give' in all ways 'unconditionally' you won't be disappointed.
