For todays ROF, what about working with a coworker and help them with learning something new. If your are more junior, ask a coworker if they can help you out with on something that either you’ve been struggling with or just want to know more about it and they have experience with it.
If you’re a one person shop, go on to YouTube, pluralsight, cbtnuggets, or even linkedin learning and see if there are courses that interest you. If you don’t have a subscription to that site, see what other courses are on there and make a case to your manager for it. Most of the time if they don’t already have a learning program, they will pay the subscription cost for you. But you won’t know until you ask. Don’t make the decision for them.
Never stop learning and improving.
