It is very simple. Follow the prayer book. That belongs to the Church, not to individuals, who set themselves up as 'spiritual fathers'. Morning and evening prayers, and force yourselves to do them day in, day out.http://orthodoxengland.org.uk/qa3.htm
If in a hurry in the morning, read them on the way to work or substitute with the Jesus Prayer, said secretly and without any display of prayer knots (which are to be kept in the pocket), not showily wound around wrists as decoration). Alternatively get up earlier!
Prayer rules are for monasteries. Follow the Church. It is simple, do not invent things that the Church has not appointed.
