what I need to do

I’ve been feeling unsettled lately. I have ups and downs, my rhythm is all over the place. I feel like it’s making me tired and distracting me from what I need to do. Or maybe I’m just looking for excuses to get away from what needs to be done. I feel like I know what I need to do, but it’s getting harder and harder every year to change myself. Thoughts become actions, so I want to be conscious of my thoughts in order to bring myself closer to my ideal, even if it is only little by little.

make a list

I have been very busy lately. Therefore, I couldn’t write my blog. Finally, now that my busyness has calmed down, I would like to spend my weekends posting blogs and catching up on technology. I updated my MindMap. I made a list of technologies I want to know about. (by Notion) I started living with a dog last month. He is a puppy, but he will be quite large.
