Everything we do we do in the hope it will increase our experience of love, peace and enjoyment. AND, no matter how much we do in the physical world, it's never quite enough. That's because to fill that void we need to realize and experience we are already all the love, peace, and enjoyment we will ever experience, that ever exists.
Accepting this allows us to take actions imbued with these qualities and paradoxically be more effective in the world. We just don't expect the actions to create the feelings we are already experiencing. The actions express what we are feeling, they don't create it.
Understanding this is the only way to take control of our own experience of life as opposed to believing other people dictate our experience of life.
