If we become too engrossed in the past, it can have a detrimental impact on our present and future lives. Reference the past for knowledge gained and lessons learned, but don't live in it. The simple truth is the past is in the past; we can't change what's already happened, no matter how we try. But, you still have a whole life ahead of you to focus on and build.
Today, let's all take a moment to consider the parts of life we're thankful for. It's true that we will always encounter obstacles and hardships throughout life, but even on our worst days, and in the toughest times, there are so many things to give thanks for. Just to be alive and breathing is such an amazing experience, and a wonderful opportunity. We can choose to dwell on the negative parts of life, or we can concentrate on those that are positive and enrich our lives.
Rather than agonize over the progress of other people, let's focus on our own, and work on improving ourselves the best we can.
