How do I actually upgrade my life?

Real contentment comes with knowing Jesus Christ in a deep way. That's why Saint Paisios, he said something like, when you're looking for peace in life you won't find peace, but if you're seeking after Christ your life will become peaceful. Man's real need, desire, inclination and fulfillment are found in his relationship with Jesus Christ. That is the real way to upgrade your life. How do you want to upgrade your life? Fast more, pray more, go to services, read the lives of the saints and be encouraged. Breathe some wind into your spiritual sails, and you'll be very content with what you currently have. You won't constantly be looking for something else to make you feel fulfilled or happy.
