Some say, doing only what’s best for us is boring. Eli Wamberg said: you have been born to sin, so sin.
You might not be ready for what yoga could bring you. You might need to live. You might need to pass certain expereinces. And those might make you yearn for some real substance to your life. Than your yoga practice finally might make sense.
On the other hand, if you mean by yoga a physical discipline, fitness, body culture, perhaps relaxation tehnique … and you are bored by it, nothing stops you to try something else. All these results can be achieved in countless ways. Just find what you feel drawn to.
