Choosing a right career pathway?
Your question is not really about Academia, it is more of "figuring out what to do with your professional life".

Academia can certainly help you in the following ways:


you might take several courses from different areas like Psychology, Animal Behaviour, and many others to find what you are leaning towards.
those things might inspire you to get a certain graduate degree. However, going into a graduate school is a big decision, and will require time/money investments, so have to be chosen wisely and not instantaneously.
it can try to accommodate interdisciplinarily (software engineering + something else) research if you decide on going to a grad school.


But you certainly have to take the following things into consideration:


not every hobby can/should be a profession. While it is awesome to do what you love and follow your passion, you have to really understand how different are the professional and amateur ways. That can be achieved by getting experience in those areas, both from the academic and professional directions.
advice/support from your family and friends will be important. Though they might not immediately support you in your immediate decisions (which depends on their personalities), you will need their opinions and wisdom.
you seem to have a very scattered vision of yourself, combining psychology, animal behavior, entrepreneurship, software engineering, etc. You might want to explore those things one-by-one but in a quality way.
getting rid of software engineering completely doesn't sound very good. You may want to incorporate your knowledge in this area to some other (like psychology) and take advantage of interdisciplinary research.
changing career path comes at a cost of suffering from the shortage of money. You will need to think of backup options to support yourself, especially if your family is not totally aware of your plans.
