Lord knows i've made my fair share of mistakes. The key is to learn from them and don't dwell on them. Easier said than done i know especially for those seemingly colossal mistakes we have each made at some point in our lives.
Here's a bonus tip for you... I've heard it said many times and most recently by a good friend, that wisdom is having the ability to learn from the mistakes of others. Yup, that's right. You can actually glean lessons without having to endure the challenges of making the same mistake. Isn't that just ideal?
Mistakes are gonna happen, that's just a fact of life. Just don't let mistakes keep you from pursuing your dreams and goals!
