Not everyone is meant to work an office job that requires sitting in the same spot from 9 till 5. There is nothing wrong with an office job, and at the same time, there is nothing wrong with wanting something else for your life. There are plenty of ways to make a living, so there is no point in forcing yourself to do what everyone else is doing because that is a surefire way to become miserable after some time. If you know what you want to do in life, then you might as well give it a go. The worst thing that will happen is failing. If you want to become an alternative healer, or if you want to become a yoga instructor, then, by all means, give it a shot. You should look into Marianne Wells Yoga RYT for training and other opportunities for starters.
Becoming a yoga instructor can be incredibly rewarding because you will find all kinds of people coming into the yoga studio/space to you. People dealing with emotional problems, physical limitations, trauma, or just people looking to find some sense of peace. Your studio, and the way you teach them the practice of yoga can transform their lives for the better. It might not be that case for everyone, but yoga can have long-term benefits for both physical and mental well-being in any individual. You can choose to specialize in a specific type of yoga, and if you want to work with traumatized individuals, then you will have to study further to become a trauma-informed yoga instructor.
At the end of the day, you will be doing something that you love, make a decent living out of it, and also watch people around you go through a transformation in your studio.
