The good thing about being an artist is that you can convert your troubles into art and profit. Especially if your problems are are bad, health, alcoholism, procrastination, headache, drug abuse, problems in family and similar stuff that many people can identify with.
The bad thing about it all is that it kills your willingness to ever solve these problems. So many artists are addicts and their personal life is a wreck for that reason.
It's easy being an artist that normalizes common problems, harder to be an artist that lifts the viewer towards inspiration, victory over self and finding strength to solve ones problems. may that is what separates a common, mediocre artist from a good one.
