Self-talk is not something you notice once and fix for good. It is a habit, and habits are built by repetition: in the sentence you keep repeating to yourself, and in what you watch, read and practise. These videos are short bite-sized pieces of information that will help with negative self-talk.
What you tell yourself shapes how you feel. How you feel shapes what you do. What you repeatedly do shapes the results you create. Self-talk sits at the start of that chain, and video is simply another way to catch it while it is happening, not after.
New videos will appear on The Self-Talk Effect YouTube channel and you can subscribe here. I will include some of them here as they are published, so this page will keep growing. If a pattern, worry or moment keeps coming up for you (before a hard conversation, after a mistake, in the middle of procrastinating) there is a good chance there is already a written guide for it on the blog, and a video will follow it.
