It's sociology time y'all ;)
Thinking about sociological concepts such as socialization, social control, and even aspects of social psychology such as coat switching... I would say no, because we don't really control anything in our own lives deep underneath the surface. Everyone influences each other in society as we grow, learn, and have new experiences throughout life. Our lives and every aspect of them are shaped by one another. This includes our goals, hobbies, dreams, leisure, etc. We are all influencing each other as a part of society as humans are innately social beings. We thrive off of learning from others actions. So, while we do have a surface level of control over the choices we make, concepts deeply rooted socialization and things we learn from those around us shape our being and influence our subconscious thinking. So, from a sociological perspective, as long as you are living among others and taking in information from them either verbally or nonverbally, you are and never will be in control of yourself. Sucks, right? TIP: don't study sociology if you want to love the world
This also gets into the philosophical argument of "what free will is and how one can attain it" that is as old as time. But I think another thing to consider in this is the concept of agency, or the idea of having control over oneself.
In sociology, we talk about forms of agency as the ability to have greater control over others, gained through high amounts of social power, status, and wealth. The more of even one of these things usually makes it easier to obtain the others, which, gives you the ability to influence what OTHERS perceive as happiness.
Then again, as the saying goes, money can't buy you happiness. So we're back to square one. Overall, the most you could ever really do is have control over others perceived happiness. Not to mention all the multitude of things created by humans that restrict us within society such as laws, morals, and norms. ANYWAY, rant over <3
