Well first of all i definately agree with everything that “WELLINFORMEDYID” said! I was in sem this past year and it deffinately made a huge difference to me that i wrote down what i wanted to accomplish! at the end of the year i looked back and boy did i feel accomplished! You can even mark down in your calender every week something else to work on (something small ex:making sure to smile at everyone etc…) and iventually it will become habit!
One thing i grew a lot in is Tifella! GO TO THE KOSEL A LOT! The more you go the more you feel a kesher towards the kosel/hashem! And whatever areas you are hoping to grow in daven that hashem should help you! All you have to do is daven and a little hishtadlus and hashem will do the rest!
