Changing your career path and not having any idea about why you want to do next is somewhat an issue that many people face. The thing about this is that the people who have these issues are much in society, and they talk to themselves about other things, but not on this issue.
Many times, you need to accept that you should push yourself into taking actions rather than making some calculations or thinking with no action. You have got to discover yourself, and know your interest. Do not be your own obstacle while you are just lamenting inside about a change. You have to make the change happen yourself.
Another major thing you should do is to make a close relationship with the right people, people that you feel they have what you don't have, and also have what you are looking for. Most times, you need people to provide you a solution to a challenge, but you will not find a solution in them if you do not take it to them. But mind you, the right people!
