Life Is Not Perfect

Go ahead with life as it is, with the bumps and pitfalls. However it is, give your best to every moment.
Don't spend your time waiting for the perfect situation, something which is not very likely to come.
Life is not perfect; the way you live can make it perfectly wonderful.

Life Is Wonderful

Face your past without regret.
Handle your present with confidence.
Prepare for the future without fear.
Keep faith and drop the fear.
Don't believe your doubts and never doubt your beliefs.
Life is wonderful if you know how to live it
