Don’t let the actions and behaviors of others affect your self-ego.

A realization: one of the downsides of altruism (or trying too hard to be “selfless” or help others):

When others act in a way which is contrary to your personal beliefs or morals, your own personal ego and self-esteem is hurt.

Then perhaps the goal should be to best try to help give suggestions and ideas to others but don’t bind them to your suggestions. Or in simple words:

Give others your suggestion, but don’t expect them to do what you suggest them to do.
