OT, be the best Jew you can be. Don’t look at others, look at yourself. Remember that you are always standing before Melech Malchei Hamelochim. Don’t miss the obvious opportunities to do mitzvos. Try NOT to miss the less than obvious opportunities to do mitzvos. Do the best you can, then strive to do better. And…..well….yup…thats about it.
As far as fear of dying is concerned, I used to be terrified. I don’t think about it anymore. Maybe because my parents are gone, and if I died today I feel they would be there waiting for me with open arms to walk into, so it won’t be so scary. I have lost many people that I love, so I guess in my mind it would be a reunion with those who I admire and love. What would I miss in this world? I would miss my family, my kids, my grandkids, etc. But Hashem has been very good to me. I have a lot of nachas from them, and if Hashem decided to take me home, then he wouldn’t decide that I have had enough nachas, he would decide that I have suffered enough pain on this world.
