[Five words: fretful, cardinal, appreciable, spur, boundless]
Recently, I have felt overwelmingly fretful about my personal growth and development. In the beginning, I was highly spurred by the idea to read and learn more extensively, aiming to gain not only salary from my job. Therefore, the cardinal task for me is to make the best use of my time, working more efficiently thus earning extra time to learn by myself. Yet you know, knowledge is boundless and it's tough to make appreciable progress. Meanwhile, the older you grow, the more pressure you're bound to feel, which can only be mitigated by either making more money or making yourself more competent. This may be the underlying reason for my anxiety and worries.
