Jolly- It is very admirable that you want to work on this-everybody needs to work on their kavanah, and it is always something that everybody could do better. There are many known paths to improving kavanah, so let us know a little more about what works and doesn’t work for you –
All the suggestions here are excellent –
If you are distracted because you have to run to work or stuff, then get up earlier so that you can daven with nothing on your mind. Take a minute before you daven to realize that this is the most important thing you have to do, as it is the time to connect with the One who will control everything that happens to you that day. Daven for everybody so that your tefillos will be personalized, and if you daven for someone else, your tefillos get answered. Daven before you have a tzara, so that you can avoid the tzara. Visualize… Picture the malachim coming to take your tefillah, and be realistic about how careful you would be to send a present to a king…picture them scorning your hurried contribution. Picture being in the position that the bnei yisroel were in, at krias yam suf, and try to sing the praise as though it happened to you-when you were totally surrounded by terror, and you got saved in a most miraculous way
let Modim be a list of reasons that you have to thank Hashem, When you say Gomel Hasadim, think of all the chesed Hashem does with you, beg Hashem for refuous and yeshuous for all the sick people, all the people who have no parnassah, and have to leave their homes to go collecting, all the singles who have not found their zivug, all the couples who need children, people who suffer with sick spouses and children-there is so much heartbreak, these people bawl to Hashem, help them.
