Look forward with hope, not backwards with regret.
Pray for your future. Do your part and have the faith and hope that you will see God's plan for you and you'll follow that path in everything you do. As for the past - remember all the blessings and allow your gratitude to fuel your optimism.
For I know well the plans I have in mind for you—oracle of the LORD—plans for your welfare and not for woe, so as to give you a future of hope.
