Answer:
B. pursuing self-directed learning
Step-by-step explanation:
It is B. I am going to explain each option.
A. obtaining a college degree
It is important. However, in the TI area, there are many good professionals without a college degree. And, if you are not dedicated enough, the college degree is not going to help you stay employed and being offered promotions.
B. pursuing self-directed learning
This is basically consistent improvement, when you seek feedback from your skills, and uses this feedback from your improvement. This is the most important factor for staying employed and being offered promotions, as the market, especially TI, is constantly changing and we are never finished products. We keep up with the marker pursing self-directed learning.
C. showing professional behavior
This is important for anyone, right? So it is not a differential for staying employed and being offered promotions, as this is just what is expected from everyone.
D. setting long-term goals
These goals have to be achievable, you have to show how to achieve them. So again, just setting long-term goals is not going to be enough. These goals must be good, profitable, etc, and this happens when you are always improving, that is, pursuing self-directed learning.
