In the measure you love yourself more, you become a radiant force of love to what surrounds you.
Yes! Not just people, as you know, but all that surrounds you.
How do I practice self-love? Not through actions. I'm not sure if that is the advisable, but what I've been working on is acceptance, on easing and ending the judgement and badgering of myself to act differently. I think that's the beginning. So I tell myself "I love you", even when I'm smoking a cigarette, or bingeing on Netflix instead of writing, or whatever I'm doing that I don't really feel I 'should' be doing. I think the vibe towards oneself is most important. I suspect (hope?) that when I have that vibe on a regular basis, and I'm getting there, then it will flow into my actions more.
In the end, the vibe is all that will go with you everywhere, so I feel your approach is a good one. More acceptance, less judgement... sounds adequate and I wish you success in your practice of this.
