I'm having trouble with running a successful business
I'm saddened to hear that. Why do you think you're having trouble?
I've lost interest in the company because once you've lost money it's hard to start fresh and make a profit each each time.
Running a business is really hard. You shouldn't get discouraged and keep trying through the difficult times.
I don't care about my company, I'm just going to quit and start over again. I need to make another company.
I feel like creating a new company is not the solution here where you may end up on the same boat in the future where you currently are on right now, so I do recommend that it is wiser to just try to recover with your current company and strive to have it profitable. Creating a new company may be more difficult to do and nothing is guaranteed and you may lose more money in the end.
