Get inspired by your past

I have noticed that various aspects of my past always motivate and inspire me. When i am down and there is nothing challenging to be involved in. At such times life looks boring. Here when intentionally or unintentionally i go through my past achievements and good memories it has great effect and i realize that challenges are still there and i would be successful as before and also it enhance my believe on Allah and i get thankful for His guidance and mercies upon me.
So try to have a glance at your past achievements to get motivated.
