There are far better things ahead, than any we leave behind.
Choose to look ahead. Think about it. If we choose to navigate our cars and drive forward while focusing intently on the rearview mirror, chances are, we are in for a big accident and a big amount of destruction. This is a great analogy for how we should live our lives well. If we choose to live our lives in the hope of moving forward, but with our hearts focused on the past, sooner than later, we will wreck our lives.
The past is a past for a reason, and that reason was to help make you who you are now, and to help give you the drive to become the person you ultimately want to become. Remember that there are always far better things ahead of us in our lives than there are that we were forced to leave behind us.
In the course of our lives, we may have made mistakes, failed, acted foolish and many other things. But at the end of it all, we realized that some, if not all of these were just sacrifices we endured and risks taken, in an attempt to better ourselves and others. And surprisingly, some are even ready to dare more.
But however we want it, we should remember to move on from what was, so that we can better focus on what is and what will be.
