Sometimes Allah destroys your plans, before your plans destroy you. Because, Allah knows, but you don't. Life will not go the way you planned and that's okay. Because Allah has a beautiful plan for you; you just need to believe it.
Most importantly, anything that you want in this world, any Dua that you're making that you feel like is impossible- It is impossible because you think it's impossible. Allah says, "I am what you think of me"
So just learn to accept things and trust in Allah's plan. No matter what! Always remember this- Everything happens for a reason, say Alhamdulillah. Whatever Allah does is for your own good.
