Positivity
Optimism is a happiness magnet. If you stay positive, good things and good people will be drawn to you. (Mary Lou Retton, American gymnast)
Few people are neutral when it comes to their perspective on life. Some are mostly negative; often seeing the thorn rather than the rose. Optimists, on the other hand, ignore the thorn and rejoice in the blossom. Retton has observed that people who think positively attract the most friends. And their influence often produces happy outcomes.
You have greatly encouraged me and made me happy despite all our troubles (2 Corinthians 7:4).
