Sometimes being meikil is necessary for a variety of reasons or another.
If a person has a poor attention span, some ADD, or dyslexia, for instance, they should probably not attempt to daven everything in the siddur; for such a person, shacharis consisting of brachos, baruch sheamar, ashrei, yishtabach, krias shema w/brachos before and after, amidah, ashrei, uva letzion, shir shel yom and aleinu is enough. If a person is prone to sweating and suffers body acne, perhaps wearing wool tallis katan isn’t advisable. Sometimes people have to do the best they can to keep halacha given the limitations of health, disability, economics, family dynamics, etc.
