Recently, I have been thinking about how to be present at the moment and enjoy my life as much as possible. I've thought about how we can prevent over-thinking about the past (which causes depression) or about the future (which increases anxiety level). After a long time of thinking and struggling with myself, I found that we should not force ourselves to think only about the present moment. In reality, the human mind is not controllable. It flows everywhere from the past to the future. On the contrary, we should allow our minds to be free. In fact, in order to enjoy our lives, we should try to increase our self-esteems not to control our minds. In other words, when you are satisfied with yourself, your mind automatically stops over-thinking about the past. Also, when you really love yourself, you look for your interests, and you will do whatever that makes you happy. So, in my opinion, if you want to enjoy every moment of your life and be present at the moment, you should love yourself, accept yourself for who you are, don't compare yourself with others, don't under-estimate yourself, and believe that you are unique. I mistakenly read "thinking of" instead of "thankful of" in the question. 😁 sorry every one.
