i do the same, in fact on the weekends i fast similarly to what one would do during Ramadan. and i devote the bulk of the weekend to spiritual study. i also think about how Islam applies to my life throughout the day, and pray to/ worship Allah all day during work. often times i hum a contemporary Muslim tune, or repeat the words to myself. and i have found i am much happier and at peace with others just by doing these things. and a genuine smile doesn't hurt.
i am looking for the ayat in the koran that touches upon what you said and still looking.....
for how islam applies to my daily life ---- well, i wake up in the morning to sounds of nature - that's my alarm clock and then i hear the plow truck. i just want to pull the covers over. i ask God to help me get through the day. and should today be my last day on earth, then to make my exit be with honor. most of my thinking/reflecting/praising God actually takes place in the bathroom as it takes me about an hour to get ready. as i am brushing my teeth, i am thinking about stuff. i look at my reflection in the mirror. i find myself thinking about things we discuss here while taking shower. lately pretty much every morning, theres snow to clear in the driveway, as my lips and hands are near frozen - i am praying to God for early spring. but i do look at the snow on rooftops, tree tops and think how beautiful it is! the other day, i just stood there looking at the snowflake in awe. of course, after i spent good 40 minutes clearing the driveway and the plow truck dumps more wet heavy snow and i just want to scream, i start complaining to God. i get to work - yeap another day. and i ask God to help me do the right thing and live right by God. when i feel stressed, i ask God to help me. when i feel like just screaming at someone, i ask God to help me calm down and to be nice. when i feel exhausted from lack of sleep or feel the pain in my heart (from divorce) is just about to explode, i ask God to give me the strength to go on. after work, i head to the gym for an hour or so. another chunk of time when i go into my zone, thinking/reflecting/talking to God. every day now, i thank God for my current job as it is not as stressful as my previous of putting in long hours, not even having time to go to the bathroom and not having time for my hobbies. living alone, i do feel afraid sometime but immediately i call upon God and i feel calm. i usually sleep with the quran next to my pillow - don't know just find it comforting. when i am not working, i am cooking, cleaning, doing household chores, doing my hobbies. of course, posting on the forum!
well...i could go on and on but everything i do in my daily life from watching tv to eating to going to work to working out at the gym to helping people to cleaning the house to reading the koran.....all are application of islam in my daily life.
putting a smile on someone's face, saying a kind word, doing the best that i can at work, being a better person....all of these is what i consider practicing islam. at the end of the day, i just hope that i have lived an honorable life and earned God's blessings. with each passing day, i am one day closer to facing God at the end.
