The internet is chock full of self-help type articles. Articles on changing mindset are among them and finding them can be a bit challenging. If you are serious about finding these articles though, you will find that it can be fairly easy.
Start with Google searches. There are other search engines to be used, but Google has much more in its inventory. Be mindful of the words and terms you use when searching because if you don’t initially find what you’re looking for, use different terms on your next search.
If you still cannot find exactly what you need, other search engines may do the trick. Using one term or one specific set of words can yield slightly different results from other search engines. As they say, where there is a will there is away. Don’t give up. You can do this.
