Plz share some challenges of solopreneurs and early-stage entrepreneurs

Hi, I'm Chris, a senior college student from South Korea, reaching out to solopreneurs and early-stage entrepreneurs for an interview.
I am currently researching the most significant challenges faced during the early stages of building a startup. My goal is to gather insights that will help me create a startup aimed at solving these very problems.

I would greatly appreciate it if you guys could share some of your experiences and concerns from your journey as a solopreneur/early stage startup founder. Your real-world insights would be incredibly valuable.

1. Basic Information

Could you briefly describe the business you are currently running, including its name?

2. Challenges and Problem Identification (1-2 items)
   What is the biggest challenge you are currently facing in running your business?

Could you please provide more details about this process?

Why was this issue uncomfortable or difficult for you?

In what situations does this problem occur? (e.g., specific times of day, particular customer groups, etc.)

How often do you encounter this problem?

To what extent do you feel the pain caused by this problem?

3. Problem-Solving Process
   What methods are you currently using to address this problem?

What is the approximate cost associated with these methods? (e.g., labor costs, software fees, etc.)

How satisfied are you with the current methods you are using to solve this problem?

What aspects are you dissatisfied with? (e.g., time consumption, cost, effectiveness, etc.)

4. Alternatives and Reasons
   What other alternatives do you have besides the current methods?

Despite having these alternatives, why do you continue using your current methods?

Thank you so much,
Those who respond to this post will be blessed for a lifetime.
