“sure i could leave my phone home on shabbos. but that’s not a big deal so i don’t see why it would make any difference.”
It makes a big difference, because you’re showing you care. You may not be able to stop doing everything, but doing what you can will help you eventually get where you want to be.
And moish, stop being so hard on yourself. So you didn’t have the best weekend ever. Bimakom shebalai teshuva omdim, ain tzaddikim gumurim omdim – if you fall, you can get up stronger than you were before. Just focus on the things you’re doing right, no matter how small you think they might be. Hashem judges every act and person according to their situation, and you never know how much one “little” mitzvah can help you.
