Self-love, basically, means you stop doing certain things. Things that limit you. Things that hurt you. Things that hurt you and don't make you happy.
You don't have to develop self-love for years to stop some destructive behaviors, you can change them throughout your life.
Don't talk bad about anyone
Stop talking negatively, both about others and yourself. Words have power and energy that you must learn to respect. Start by stopping criticizing, judging. If you have nothing positive to say, don't say anything.
Don't comment on how fat you've gotten, don't talk about yourself being stupid, exclude yourself from conversations where someone is gossiping and judging. This does not mean that you should not analyze someone's behavior and try to understand them, or that you should not confide in anyone and share your experiences. Because you still have your conflicts and difficult moments and need sharing, support and understanding.
Do this only with the intention of contributing to or gaining understanding, without labeling and pronouncing.
Don't compare yourself to others
Whenever you do this, you may feel that others are happier, more successful, more skilled, better at something than you. If you appreciate their virtues and abilities, ask yourself to what extent you can master them yourself and whether they have any practical utility for you.
Or you may conclude that you are better than others, which will feed your ego and fuel your arrogance. If such comparisons need to get you going, then you have insecurities and fears that you need to work on – and do it out of self-love.
When you truly love yourself, you are simply who you are, without feeling different from others in one way or another. Then you notice and value more what connects you with others than what separates you from them.
Do things your way
It doesn't matter how others do it or what is generally accepted as the right way and what is valued by others and the environment. Do things your way.
Listen to yourself and your heart and follow your path. If it means leaving a secure job where you are unhappy to develop your talent and focus on what matters to you, do it. When you act from deep conviction and in alignment with your being, the universe gives you every support.
Don't stay where you are uncomfortable and unappreciated
If a date makes you feel uncomfortable, boring, and irritated, walk away. If someone has treated you badly, confront them or simply cut off contact without explanation. If they don't value your creativity and knowledge at work, find a job where they value you more.
Stop neglecting your physical and spiritual well-being
Every form of self-care is equally important. Working on spiritual development doesn't mean you have to be messy. Nail care, massage, exercise, care are just as important as reading, meditation, connecting with nature, breathing, healthy eating. Nurture your body, your emotions, your mental health, your intelligence and your soul.
Be who you are with all your might.
