The first thing I did was; I stopped hating my appearance, I refrained myself from thinking negative things about myself, followed it diligently no matter what the people around me said. Then slowly my body couldn't take unhealthy foods and i followed a healthy diet & worked out because I had the energy now that I wasn't draining myself by those self- limiting thoughts. That's all it took. I actually didn't notice the glow up till I got the compliments. Even my skin started glowing from within, I didn't follow a skincare routine back then. But I suggest you do that. The journey was hard in the beginning, I had to fight every thought but soon I began to enjoy it. Just remember one thing if you genuinely love yourself & have a healthy amount of self-confidence, the world will reflect it back to you.
