What´s the reason why it´s difficult to you? You don´t find time or remember to pray? Don´t you have enough enthusiasm for it or what´s the reason? Try to find the reason why not and solve the basic problem what prevents you to pray.
For example; make a daily schedule for praying. Check it many times of the day and it helps you to remember the times you have to be ready for praying. If reason why it´s hard to you is something else, try to think how to find ways to make it easier.
