Many people in this world are always questioning this, what is a good business? Well, good business is a business that begins, rather than being questioned because the hard thing in doing business is to walk to the first ladder. If we do not start a single step, we will never get to the top. Just as with trading, or investing in cryptocurrency, without trying and starting investing in it, you will not know how much profit you get, and how much experience you will receive if the market is down. Remember that experience is the best teacher.
I've read quotes like this, whether you quote them or not, but I really agree.
The toughest things people who want to start a business are fearful, afraid that the business is not successful, the afraid of selling unsold, and the other fear that prevents the person from starting a business. In fact, all the dreaded is part of the ladder of success that we must pass. Build customer trust so the company name will skyrocket by itself because in business, consumer trust is one of the main factors. no consumer trust means no profit.
Totally agree with both of your points, in addition when starting a business or any other investments a businessman or investor should treat every losses as a motivation to strive to be successful and learn form it, as complaining will do a person nothing and just upsets. Remember that many franchises and companies started in the bottom and they to have had their own challenges and mistakes, there is this quote from the one of Sylvester Stallone's movies:
"Let me tell you something you already know. The world ain't all sunshine and rainbows. It's a very mean and nasty place and I don't care how tough you are it will beat you to your knees and keep you there permanently if you let it. You, me, or nobody is gonna hit as hard as life. But it ain't about how hard ya hit. It's about how hard you can get hit and keep moving forward. How much you can take and keep moving forward. That's how winning is done!" - Rocky Balboa(2006)
