Make an effort to be a genuine person. When you say you will do something, do it. When you ask someone how they are doing, wait for them to answer and really listen to them.
Be a genuine friend, spouse, brother, sister, daughter, son, co-worker, boss, etc. Work hard to be comfortable in your own skin and a genuine love for others will follow.
Being a genuine person will make your relationships stronger which will greatly enrich your life. As a genuine person your actions will inspire and encourage other people around you. You will be a role-model.
Help others to lead genuine lives as well! Set the example for them to follow. Always be ready to listen and offer advice. Always be honest, both with yourself and others. If you don't have time to do something, then don't commit to do it; you can be a genuine person and still say "no" sometimes. When you are serving others, do it out of a genuine love for them, not out of a sense of duty. Live your life in a genuine way and always treat others the way you would like to be treated.
It can be overwhelming to think you have to change your entire outlook on life in one day. Start with yourself! The more comfortable you are with yourself the better prepared you are to share yourself and your life with others, which is the first step to genuine living. If you are able to be honest with yourself, it is actually rather easy to be honest with others. Some other ideas: take up role models that you think are genuine; surround yourself with genuine people; and write down why you feel being genuine is important, so that you yourself are convinced of your goal.
