When the project fails, ask whether it was worth it or not and if the answer is “yes”–Try again.
“Success is not final, failure is not fatal: It is the courage to continue that counts.”
Winston Churchill
This is an example of applied optimism. Look for the bright side. Work toward a successful completion of your project. Figure out how to solve or correct your problem. Examine whatever is making you unhappy and deal with it.
And if you do all of that and fail? Well, then, summon up the courage to start all over again and go after it.
And whatever you do–Keep on smiling…

Again, you’re spot on. Life itself is the greatest project we have. The only project, really. And it ain’t over til it’s over. If you goof up some part of your project, try to correct your errors. Most, but not all, things are not final and are correctable. If they are not, accept that and put your energy into doing better. And forgive yourself. With any luck, if you’ve hurt someone in your failed project, perhaps they will follow suit. And never, never give up. That’s it in a nutshell, a bit of what wisdom I’ve gained in 69 years.
