THE most important thing? Do everything as if you are doing it unto the Lord. It changes every single thing you do and how you think about it if you are working for God instead of yourself. At that point you are just a steward of God's land, His chickens, His provision for you and yours and you can relax into the whole thing. Every big decision is His, all things out of your control are in His so if you have drought, too much rain, too many pests or just don't have good crops for any reason, predators get your chickens, etc., you don't have to stress about it, because He's in control. You've done your best but He's in control, so let it go.
When it's approached in that manner, it's all very exciting and peaceful, full of good things to experience and learn and you can start and finish each day in gratitude for the One who lets you live that kind of life.
