To keep yourself and your business running at optimal levels, spending 5 minutes checking for any software or app updates is a nice quick win. How you do this will depend on the computer/phone you're using but in either case, it shouldn't take too long. Apart from when it comes to massive system updates which are generally inadvisable if you've got a lot of work to get done - these are best done overnight or when you're not working.
Something I didn't know before writing this: a lot of cyber liability insurances have made it a requirement that you have fully up-to-date software or your policy will be invalid. Another reason to hit the update button!
