People often complain about gratitude for a lack of appreciation and how it has affected their relationships, health, career success, etc. This is all very true. The problem comes from not knowing how to actually cultivate a grateful mindset.
The Benefits of Gratitude and How to Cultivate a Grateful Mindset
You can start by becoming aware of your thoughts and feelings as you're feeling grateful. This can help you identify the underlying cause of your gratitude and what you need to learn to feel even more grateful.
Another helpful technique is to reflect on the things you've received. You'll find it easier to recognize your blessings when you put your focus on gratitude.
Finally, practice positive affirmations. Say to yourself "I am grateful" every day and see if you feel more appreciative after a few days.
