The next big thing is to know and believe that you deserve happiness. Yes, YOU do! Perhaps you believe you don’t deserve to be happy because of some mistakes you’ve made. I completely understand why you believe that, I’ve made some horrible mistakes that I regret. Even so, we all make mistakes; it's part of being human. The best thing is to learn and grow from it and move on. Even though you’ve made those mistakes you still deserve happiness and joy in your life. This may be the hardest step to embracing positivity, but you truly need to know and believe that you can have happiness and positivity in your life. Sure there are and will be hard times in life, but you can have happiness. 

It might seem like an uphill battle. And well, it is at first. Our brains are wired to see the negatives first because of our fight or flight instincts. When we see a challenge we need to overcome it. For example, if there were a saber toothed tiger in front of you and about to attack, you would need to notice that before you notice how beautiful the sky is so that you can decide whether to flee or fight it. In this day and age, noticing the negatives first doesn’t really serve us. We can make that instinct to see the negatives first switch into seeing the positives first. Look for the positives and the good things in life, be aware of them and engage with them.
