Lynsay Sands said this quote

happiness is a choice. If you choose to mope and be glum, you shall be; but if you wish to be happy and determine to enjoy what life has to offer, then you can have that as well.“She said that nothing is all good or all bad, that life offers everyone a mix of both—though sometimes it does not seem so, and bad is all we can see in our lives, while in the lives of others we see only good and feel envy. She said we must enjoy the good despite the bad, else life can beat us down and leave us hopeless, and that is no way to live.
