The process of nurturing love in yourself is very complex and painful, to say the truth. For some, it can go quickly, but for others it will take a lifetime.
Love for one's neighbor is self-digging at the first stage. If you dislike people around you, in fact, the problem is not in these people, but in you, in your idealism.
A person can be anything bad, but in his environment there will always be people who love him, despite all his shortcomings. If you do not love him, begin to cultivate tolerance in yourself, and you will already embark on the path of love for people.
Probably heard a saying about a speck and a log in the eyes. And there is some truth in it. The process of dissatisfaction is usually a projection effect. Its essence is that the psyche subconsciously disguises our own compromising material. And the best defense is an attack. For example, if you can’t endure excessive romance and sensitivity in people, this may well mean that you and yourself deep down suspect these traits.
Rummage in yourself. To do this, you certainly need a lot of courage. It is rare for anyone to easily find the transformation of their own, already seemingly established personality, attitude. Try to be honest with yourself.
Accept, as an axiom of life, the fact that there are no ideal people. Look better in people for their virtues than hypertrophy already discovered flaws. There are plenty of them in other people.
If all this is hard for you, then just smile at people - this is a step that, surprisingly, powerfully changes those around you. He is also able to change you. As soon as you notice the changes, then it's time for the more serious step described above.
