It's wise to challenge any of your thoughts, motives and behaviors that may lead you to care little for your own existence. Enjoying yourself is second in importance to survival. We do not prescribe specific activities that lead to happiness because we recognize people are very different in how they enjoy themselves. Rationally seeking happiness usually includes discovering activities you like with a focus on long-term happiness. Self-acceptance is when you acknowledge your existence and that you want to continue to survive and live happily.
People usually rate themselves by putting themselves up or down.
Tolerance of others. Accept that other people are fallible. Merely acknowledging their mistakes without damning them will allow you to deal better with their bad behavior and will give you less misery. Work is necessary for the accomplishment of nearly all lasting change. We may want to act differently, but wanting is not enough for us to have what we want.
