I always find it hard to perform Dua?

Dua's do not have to be for yourself and your own wants and needs, they can be made for anyone and anything. My Dua's are for those suffering, for those oppressed, sick and in need, for guidance for myself, my family and my Ummah and for forgiveness for that which I do wrong which I know not. Surely you can ask for guidance at the very least if you can think of nothing else? Pray for those less fortunate than yourself? How hard is that?
