That resonates with me a ton! When the rewards aren't immediate, it leaves space for doubt, but by trusting the process the benefits will start to pile up. I'm experiencing that right now as I'm introducing meditation into my routine. For me, meditation has been gradual process of uncovering and understanding my mental state. I been learning to observe my thoughts and feelings without judgment, recognizing doubt, anxiety, and anger as just chemical reactions, and not immutable truths. These feelings will arise all throughout life, but I'm learning to disconnect them from my actions and beliefs. The most profound changes in life come from within!
