Interesting answer yenajeon. As an online business owner as well, I've seen all aspects of personalities and ages in this industry, both successful and struggling.
But in regards to your question Liv, I believe that if you truly want to learn this industry and become successful, age does not matter.
I've personally met an older gentleman, previously a physician, who had begun this industry at the age of 73. In one year he was able to gain back all the losses he experienced in a previous business venture that went south.
So truthfully, the online industry is not as easy as most make it out to be. But if anyone is willing to put forth the effort to learn, then I honestly don't see an issue with age.
Hope this answer helped Liv. Have a great rest of the week and Happy New Year!
