So often it hurts us that we are not able to focus in our prayers. Remember, the more you focus on Allah outside your salah, the easier it will be to focus on Him inside your salah. What occupies you in salah, is what occupies you outside of salah. Try to fill your mind and heart with Allah as much as you can throughout your day. Talk to Him, make duaa to Him constantly. This will build your personal relationship with Him. Then, going to salah will be like coming home to an old friend.
The study of history is the best medicine for a sick mind; for in history you have a record of the infinite variety of human experience plainly set out for all to see; and in that record you can find yourself and your country both examples and warnings; fine things to take as models, base things rotten through and through, to avoid.
