The art of living is keeping your mind under control even in adverse conditions and being in equanimity and then accepting people as they are.
Not everyone will be like you, but do not go away from the relationship because they are different, and have a different kind of thought processes. Whatever the kind of person, accept them as they are and whatever way we can be of use to them, be that.
Third point is, do not be a foot ball of others’ opinions.
Fourth is, if someone makes a mistake, do not see an intention behind it. Do not think that they have done the mistake purposely. Just the way it happened because of you, same way it happened because of the other person as well. In this way, see the personality behind the mistake, recognize it and have compassion towards such person.
And the fifth one is live in the present moment. Learn from the past and plan for the future but live in the present. Whatever is there in this moment take advantage of it. Do not sit and keep on thinking about the future and do not have anger towards the past and punish yourself.
The Art of Living is based on just these five points.
