And i wont let myself down i will and surely will reach cyan rank. its already my end of 3rd year in college but the affection, the love with this platform is amazing, and am grateful for that. as a final act of love i will pour my heart and soul to climb 1400. will i then continue giving contest? dont know, let the time decide but till then am all in. the ambition small enough and yet to get fulfilled
