I try to have moments throughout the day where i let everything flow in. There are a few access points that work really well for me. Eyes open or closed, a few aware breaths, focusing on what i hear, focusing on what i see, feeling my body, a thought like "what would it feel like, if i didn't believe my thoughts [about this situation]". Sometimes it's really helpful just to have a moment between actions, say when i drive somewhere and don't immediately get out of the car after arriving or having a moment where i just sit/stand before eating my meal or after the kids fall asleep or before i start climbing. I think that's what thankfulness is actually, just accepting the situation as it is and fully being in the moment. I think different strategies work for different people, but i just noticed it had a bigger impact on me this way, than meditating for 20 minutes everyday
