I'm gonna need a new welder.

Americans have an attitude that if you fail, you must be the dirt under a snails ***.
Our culture has a very strong influence on our failures, and mostly, on our attitude toward these failures.
I personally feel the opposite is true.
Vince Lombardi once said, “It’s not whether you get knocked down; it’s whether you get up.”
I think that applies to business as well. If the business does fail, and you're willing to step back and be completely honest with yourself as to why it failed, you've learned something. Now you know what not to do. Unfortunately with us Americans, it's that stepping back and being completely honest in our assessment and finding fault within ourselves that's a real problem.
Don't worry about what others are telling you, learn to fail or fail to learn.
I congratulate you on your business, and I hope you need to buy even more welders and need people to use them!
Good Luck!
