Very good question, @faianmani. Of course, it depends on the specifics of what you're taking about. However, yes, you have to make decisions in life on what to do. Base these on the core principles that matter most to you and what your long-term goals are. If, for instance, someone chooses to become a medical doctor, that means she/he has to say no to other options including other activities, at least while attending medical school. This is why it is important to know your long-term goals based on values you carefully embrace. Thank you for stopping by. Nice to hear from you.
