I once had a friend that was very cautious. She would suggest that I not try certain things, in fear that I might fail or somehow get hurt. I believed her until a new friend blew up that idea on life/love.
The new friend would say, “are you crazy, go for it.” My life expanded at that moment, not only because of her positive attitude, but also because I had someone who now believed in me. Surround yourself with people who cheer you on and be that friend for those who need cheering.
