You should see the fun in the world instead of dwelling on the unhappy things.
Take each day and live it, love it, it might be your very last day here. Don’t be aggravated, don’t aggravate anybody else, and just keep a smile on your face. You’ll be happier, you’ll be happier, and everyone around you will be, too.
Try to remain upbeat, no matter what, and never lose your sense of humor, even if you’re jokes are awful. Keep cracking your jokes to whoever you see. Find something fun and pleasant and happy to say to them. You’ll be much happier and lead a much better life that way. Look at the glass as half full – be positive – look at a problem as to how it can be made to work out, not that it cannot.
