You do not owe anyone any justifications for your actions. If you snapped at someone who did not deserve it, simply make a heartfelt apology, once, and move on. You don’t have to apologize over and over again. If you were sincere and meant it the first time, that should suffice.
You must decide who you want to be and maintain your standards no matter what anyone else thinks, does, or says. Don't allow the actions of other people cause you to lower your principles. Never stop being a good person, because of bad people. Don't give anyone that kind of power over your life.
There is something that we all need to take to heart - you do not need anyone's approval to live your life as you see fit. In addition, you do not owe anyone any justifications concerning how you choose to live your life.
The key to happiness is simply being happy no matter what is happening around you. You have no control over the rain or storms in your life, but you do have control over how you respond to them and whether or not you will decide to be happy...
You are responsible for designing and manifesting your world as you want it to be. You are the artist and your world is your canvas.
You have no control over external circumstances or events, but you do control how you choose to respond to them. Inner peace comes not by trying to manipulate people, circumstances, or events, but by realizing the power that you have within you - the power to choose your thoughts, words, and actions.
You have to learn to trust your own opinion and your own thoughts, more than those of other people. If you will get quiet and learn to go within, you will find the answers you seek.
Speak in such a way that others love to listen to you. Listen in such a way that others love to speak to you. Words are important. They are much more than a way of communicating with others; they contain power and energy. In addition, the way that you say something, and the intention behind your words, affect the energy that your words contain.
This is a question that each of us should consider every now and then. Would you like you, if you met you? If the answer is "no," then you should ask yourself, "Why not?"
Always remember that your present situation is not your final destination. The best is yet to come! The one thing that you can always count on is change. Everything is changing all the time. You never truly know if something will end up being good or bad until some time in the future.
