Your voice needs to be heard --- not necessarily by the race on other planets --- but at the very basic level by YOURSELF. You need to know what you sound like when you talk, and the stuff you say when you talk. I have been talking to myself since I was four and I know that for a hard fact. No --- I do not have a problem. I am just born special --- with the ability to start a conversation with myself and carry it on.
You can use any medium to hear your own voice. Self-talk can be done before a mirror, without a mirror, or recorded on video or just audio and replayed to oneself. The idea is to use your mouth and then let your ears hear and brain to process. Sometimes, the person inside us has an important message that we are deaf to.
Despite the self-talk I heard myself talking for real when I recorded the Radio'TV vlog series. There was an instant jolt of self-confidence because I sounded almost like an RJ there. I discovered something about my voice that day --- it has talent.
Voice yourself --- find out what your sound like!
