According to Forbes, Physical Therapy ranks among the top 10 Happiest jobs.
The best part of working as a Physical Therapist is getting to help others improve their health and resume their normal activities. Research has shown that Physical Therapy is among the top 10 Happiest Jobs because Physiotherapists felt their job held high meaning and about 4 in 5 physical therapists surveyed reported high Profession Satisfaction.
I think you have to enjoy being a Physiotherapist before you can be able to help patients struggling with one condition or the other. It is not a Profession you can just practice, you need passion and dedication to be successful.
