It is important to perform your simran without having any hope for rewards. Planting a seed now does not mean that the fruit will appear tomorrow. it is important to be thankful in the first place for the little things in life which we have and which we should realise that we have been given by God.
Any simran you do today is just like the seed which the farmer plants in the field. It will take time for the results to be reaped. If your eye is more on the results then you do not perform a good job in your simran. It is like building castles in the air - like the boy who carried a basket of eggs on his head hoping to sell them and kept dreaming about everything which would be possible with the money. Alas when the basket fell from his head and all eggs cracked then his dreams were shattered too.

Include Sukhmani sahib in your routine too.... maybe once a week or just listen to it. If you can read meanings all the more better. it will help you develop the right mental attitude to possess while performing your simran.
May be you are right. I should be strong mentally. My mind is playing some games. I love doing simran even though I haven't had any major experience so far but I trust guru sahib will bless me for sure some day. I want increase my daily routine of doing simran.
