Learn who you are and about who God has called you to be, so that you can move swiftly in your lane of purpose. When you know yourself, it's easier to focus on your goals.
There's a saying, "Show love to get love". Well before you can even show love, you must love yourself.
You cannot have confidence without knowing who you are and loving yourself. This is imperative because, in almost any aspect of life, it's hard to take anyone serious who doesn't seem to take themselves' serious.
There will ALWAYS be obstacles in your journey. During these times, always remain calm and give your issues to God. Stick to the the plan and always use failure as motivation. Keep God first, and let him direct your path.
To whom much is given, much is required.
