What is a good example of substituting positive thoughts for negative ones?

A good example of substituting positive thoughts for negative ones is when someone feels overwhelmed by a challenging task at work. Instead of thinking, "I can’t handle this," they could reframe that thought to, "I’ve successfully managed tough projects before, and I can do it again." This shift in perspective not only boosts confidence but also encourages a proactive approach to overcoming obstacles. By focusing on past successes, the individual cultivates a more positive mindset that fosters resilience.
