No one woke up one morning out of the blue and just outright, fully loved themselves. It takes active effort. It takes active presence. You must learn to be more self-aware. You need to find things to be grateful for about yourself. You need to practice that love. Start small, but do it every day. Write it down if it helps. Keep growing the list of self-appreciation and love. Learn to look into the mirror and love the person looking back at you. Find that self-acceptance. Accept yourself not in perfection, but in love. Love the fallible and frail human you are. Develop self-love. If you want to have a successful and happy life you need to learn to become your own friend. You must foster and nurture the relationship you have with yourself. Out of all the people in your life, the one you will be with the longest is yourself. I can't stress enough how important it is to learn to love yourself. Practice it every day.
