To love oneself is to love life. It is essential to understand that we make ourselves happy in making others happy.

we find that the optimists have an undeniable advantage over the pessimists. Many studies show that they do better on exams, in their chosen profession, and in their relationships, live longer and in better health, enjoy a better chance of surviving postoperative shock, and are less prone to depression and suicide.

[You] can dramatically change [your emotions] to be more altruistic, more loving, more compassionate, more attentive, and especially to have an inner sort of confidence and strength that you know that you have the resources to deal with whatever comes your way.

We all have the ability to study the causes of suffering and gradually to free ourselves from them....it is not the magnitude of the task that matters, it's the magnitude of our courage.

Although the optimist may be a little giddy when foreseeing the future, telling himself that it will all work out in the end when that isn't always the case, his attitude is more fruitful since, in the hope of undertaking a hundred projects, followed up by diligent action, the optimist will end up completing fifty. Conversely, in limiting himself to undertake a mere ten, the pessimist might complete five at best and often fewer, since he'll devote little energy to a task he feels to be doomed from the start.

Authentic happiness is not linked to an activity, it is a state of being.

You should really stop worrying, develop the real wish to live and with a good motivation, [such as] "I have a better life and I can put that life at the benefit of others."
