I have heard that “Actions speak louder than words.”. This happens to be an expression I agree with. Much of the time it should be possible to see what someone is about by both words and actions.
Talk is cheap. It is easy for anyone who is dishonest to say that they are a writer for example. If they do, it would look bad if they had nothing written when someone asks them what they write.
If they say that they are a guitarist, I can expect them to be willing to play the guitar and show me what they do. Same goes for any type of musician no matter how they produce their music.
It is not that a person is defined only by what they do, but I think that doing something is what makes people relevant to others as well as themselves. When someone calls themself a writer, musician, artist, doctor, christian, firefighter, police officer, lawyer, or scientist, I should see some type of evidence to match it.
Very often, people label themselves by a certain thing that they do. When I call myself pro-life, it means that I will try to do something to protect and improve all life the best I can. I don’t want to just say I believe something without doing something. To simply speak without doing something would be dishonest. The problem I will always have is that my ideas are endless but my time and money are limited. I do what I can and that is all that anyone can do.
