My character and my Life

I realised something .... I m a self-centred person ..... irritating, complaining ..... petty n rude to others. I pray that I'll change in God's power ..... I m always so immature .... like what .... when I'm angry then I scold ppl. Y I like that one? Being a christian must be loving, caring n friendly, be respectfuland must be forgiving. why m I so petty ..... see I complaining again. Szehui .... stop it !
