You do what you feel good about, which you think is the right thing you believe in and where you get your strength from. You do it for yourself, is that selfish? No, because you live your own life. As long as you do everything from your heart, your feeling and your passion, you are doing well. Your intentions are pure, because as long as you make your own choices and act from your feeling, passion and compassion, you do not hurt anyone, do you?
In everything you do and in everything you say people can express themselves angry, disappointed or jealous. Perhaps this is because they are disappointed that you think of yourself for once, instead of putting yourself aside. Maybe it is because they would rather see you go down than you are doing well. And maybe they are scared, afraid they can not make the same choices or can not achieve the same as you. But does that entitle them to attack you and take away your security? No absolutely not. Of course they may have their feelings, and may they speak out. But an act out of jealousy, envy or despair is not good for anyone.
Instead of hurting someone, hurting someone by your own sense of despair or uncertainties, first try to observe, try to read a lesson. Try to happy for someone else, give someone his luck and see it as an example. We are not competitors, we can help each other. We can support each other. We can listen to each other, and see each other and hear each other. Doesn’t it make you much happier when you are awarded? Because it is awarded to you. It is up to you, you find happiness in yourself. Focus on yourself and let others inspire you. Instead of bringing them down, help them up and help yourself.
