Celebrate the happiness that friends are always giving, make every day a holiday and celebrate just living!

Celebrate the small things, for one day you may look back and realize they were the big things.
Celebrate what you've accomplished, but raise the bar a little higher each time you succeed.
Celebrate your victories! Be verbal about it. Haters will say you're bragging, but those who love you will celebrate with you.
Celebrate the success of others. Their success is a reflection of their hard work and determination.
Celebrate your success and find humor in your failures. Don't take yourself so seriously. Loosen up and everyone around you will loosen up.
Celebrate the fact that you're still evolving. The person you are now will evolve into someone even better with time and experience.
