Things that are easy to carry as used more often. For everyday that are things like my SAK and Nitcore Tube.

But i also have a small toolbag for quick fixes, makes things quicker and easier, so more things are fixed quicker.

This also apply's to most other things; from work, hobbies (climbing, MTB, skiing, etc). If it's small and light, more likely to bring it with me and actually be usefull.

Having items that are to bit or complicated are just adding logistical stress (both in my private and proffesional life).
