You, steadily moving forward at your own pace, can achieve solid results. The more you firmly acquire specialized knowledge and skills, the more unshakable confidence you are likely to gain. If you were to lose that confidence, it might be when you are deeply involved in a topic that you completely dislike or when you lack the capacity to finish things until you are satisfied with them one by one.
To some extent, there are situations where you need to be flexible and adapt to your surroundings. However, in a job that requires you to suppress your own feelings and respond quickly, you may not be able to fully demonstrate your strengths and could become unstable. It may be necessary to carefully assess your abilities and create an environment where you can utilize your accomplishments.
