Sometimes figuring out where to start is the hardest part of starting. Don't overthink this — simply ask yourself which area of your life (faith, family, or fatherhood) needs the most focus this season. Then pick a resource and spend real time with it.
Healthy growth in any area of life takes time. So pick one resource, spend time in it, put what you learn into action, and trust the process of God forming in you what He desires.
