Much can be said about the Buddha's teachings, about the importance of meditation, wisdom, compassion, how we are all interconnected. Of course, many other spiritual traditions share these same attributes. Here is what Buddhism really gets right:
The focus of the practice is on our own mind.
This practice is going to take awhile.
You are not to jump right to benefitting others and compassionate activity. You should not get lost in working in projects outside yourself. Bring the focus inside, learn to recognize your own needs, your own wounds, your own limitations.
As you learn to open your own mind, to heal your own heart, you naturally become more open and available to others.
You can't shortcut this step. There is no escaping this requirement, if you try to avoid it then it will always be a limiting factor in your life.
You are the limit, and the throttle.
