I know what you're thinking:
"It's not about the destination, it's about the journey."
We've all heard this a thousand times and, in some way, it's true. I've enjoyed every single fight I had in my life to get me where I am today. I like the challenge, I'm addicted to the adrenaline of having to outperform myself. But:
"Lets face it: like it or not, the results are all that matter. If you "attempt" to take out the trash but only make it to your front hall, garbage will continue to accumulate in your home – and you'll have a problem. Quit patting yourself on the back for trying and save your rewards for actual accomplishment. Be hard on yourself until you get real results, not efforts!"
And this is also true. And that's why I celebrate "like a madman". It's that "work hard, play hard" music. Whenever I hit a milestone, I celebrate. Champagne, good wine, good laughs, best friends. Share with the world. The ones that matter will congratulate you and enjoy your success. Your team will also like you to succeed because your success is their success and their success is also your success. And it's like Feedback theory: maximize the effect of positive results, minimize negative results. Say all the negative stuff once, propagate good news throughout time. I'm not saying to ignore failure (failing is important), just to be really happy with success.
So, celebrate as hard as you can!
