Ask yourself how do you see yourself in 5, 10, 15 years. Operationally define how it looks like, consider does OT meets your need and what alternative paths can also meet it. Many therapists do get burnt out but I think that can happen in any field. The individual is a product of its environment but the individual can also shape the environment.
OT is a field that naturally roots in problem solving and adapting to different situations. Much like news, negative feedback will always standout. It is beneficial to get as much of the picture revealed to make an inform decision. High productivity standards, no salary growth, saturated field with difficulty in finding work, disrespect in the workforce, and theory based schooling are all credible statements. However, on the other end there are therapists that have more flexible productivity standard, comfortable wage, no problem finding work. I have met OT who wish they did another field but I have also met other disciplines who wished they did OT originally.
Going to occupational therapy school, everyone hates theory but it truly is a necessity. Theory drives evidence, it prevents people from just making things up. OT as a tool can adapt to many situations so generalizing it can be difficult for unfamiliar audience. Occupational therapy itself present differently whether you work in hospital/inpatient, school, long term care facility. These are all traditional practice areas and many have paved way to discovered their own unique niche. Many go into the field to solely focus on clinical practice but some have deviated through business, entrepreneurship, education, or research.
As an occupational therapist, I do think advocacy needs to be stronger both on the organizational level and the individual level. My job constantly is sharing how occupational therapy can benefit students, teachers, and family. I think lack of respect happens because of little understanding. True collaboration working with clients and other team members require open communication to meet a common goal. OT is all about overcoming barriers and that is why I love this profession so much.
