If you're mostly concerned about yourself without harming others and not harming yourself in the process... Then you are on the right way.
Being self centered is not being selfish. Those who are self-centered are NOT narcissistic, hedonistic, or self-absorbed. Because self-centered individuals are more grounded, they are able to give even more to others. They have the potential to be even more generous and to make even greater contributions.
Take care of yourself first. Be centered. Be grounded. Take control of your life and don’t get derailed by circumstances around you.
Instead of centering your life on someone or something that may not be around as long as you, maybe you should try being self-centered. This gives you some level of stability in an unpredictable world.
It can be hard in the start... But once you start relishing the outcome.. You surely can continue it.
Being service centered is good. But that can only be possible whem you are self centered. Be the centrw of your own universe.
