So I am a Fresh Graduate, 23 years old with a Bachelor's degree in finance with no job experience in my field other than some part-time job.

I have a friend who is very successful in his career as an AIA Insurance agent. After explaining to me how the commission scheme work, I was convinced that being an Insurance agent really have a lot of potential.

The reason I considering being an Insurance agent are because of the flexibility of hours, be my own boss, potential high income, and passive income. And I also working on my online business , so having flexible hours really helps. The only thing I hate about it, is the stereotype surrounding it and I don't really like sales that much however I am willing to step out of my comfort zone, if it can offer me the freedom and success (wealth).

However, there are family and friends advice me to work in a 9-5 job such as bank or other related field for few years to gain some experience first before being an Insurance agent. So if Insurance agent doesn't work out, at least I have the experience to get hire for other job.

So my questions is:

1) Is it best for fresh graduate to start working in a 9-5 corporate job first that offer stable income, or should I start with being an Insurance agent? Which is better?

2) If I work in a corporate job for a few years, will it be too late for me to start being insurance agent when I could already build a client base long ago?

3) If I work as an Insurance agent and it doesn't work out, will it be too late for me to find a stable job since I don't really have any experience in banking or finance other than insurance sales. And I would have wasted all my time as an Insurance agent and go back to square one with basis salary.

4) What is the success rate of being an Insurance agent?

I wanted the freedom and make a lot of money but afraid it would fail on me even with all the hard work and I would end up with no job   

Any help from profession or anyone would be much appreciate 
Thank you in advance for your kind assistance!
