What are some of the challenges of working as an actor or artist?

I think the answer to this question depends upon the individual artist. Everyone has their strengths and weaknesses when it comes to being an artist.

Some artists will only try to get into art galleries and shows to sell their art, others will try to sell them online, and others will create them from commissions. The real problem doesn't lie in which method an artist uses to sell their artwork, it lies in their thinking about art.

Some of the things I would think of would be having to overcome to fear of other people, as in, discrimination, hateful comments, and how good YOU yourself would think your doing.

As well as making sure you are able to remember things like lines and actions say if something was a live performance.
