I know that I have a lot of challenges to overcome but I try not to complain about it. I love to look at the bright side. I know that I am privileged. I know that I am blessed and I am not grateful enough, so why should I complain? Although I love to be positive and grateful, I have disappointing moments at times. And at such times, learning English calms me down and brings me joy. I hope I remember to learn some English every day. A thing you love must be a noun, but "look" is a verb. To make the sentence work, you must change your verb into a noun. There are two ways to turn a verb into a noun: the present participle and the infinitive. So you have two choices: "I love to look", and "I love looking". You can have "moments of disappointment" and "disappointing moments". I wouldn't say it is wrong to say "disappointed moments", but the others are better choices because people, not moments, are disappointed (except maybe in a poetic sense). So, I would say "disappointed moments" is a good poetic choice but the others sound more natural. Your last sentence is correct, but "remembering every day" sounds simpler than "not forgetting every day". I find the latter logically cumbersome. Really, to be accurate, it ought to be "not forgetting any day".
