We look forward to them all year long: summer Fridays. When the days are longer, it's important to make them count, and treat Friday like any other weekend day. Even if you don't have summer Fridays, chances are you have a few flexible days to use to your liking throughout the summer.

The only problem? Figuring out what to do! I hear so many people say that they didn't take advantage of their summer Fridays because they couldn't think of anything they wanted to do. Preposterous!

Others might feel like they have too much going on to take advantage--it is Q3, after all. But there are plenty of ways to spend your summer Friday that can actually be beneficial to you when you return to the office on Monday. Here are three places you can visit on your summer Friday to keep those entrepreneurial juices flowing.

Museums

If I've said it once, I've said it a hundred times: I love visiting museums. In my opinion, it's one of the best ways to learn, especially if you opt out of the tour. Wandering around, admiring greatness and absorbing little (or big) pieces of history is a great way to get inspired, and that inspiration can be brought back to the office and channeled into an upcoming (or ongoing) project. Taking in art created by some of the world's greatest talents is a great way to motivate yourself and your co-workers to keep working toward your own greatness, and your company's.

Plus, they're air conditioned.

A Neighboring City

Travel is a great way to spend any time off, really, but there are the usual hesitancies: the cost, the planning required, the list goes on. So if just the thought of planning a week-long vacay this summer leaves you exhausted, pick a neighboring city instead, and plan a day trip.

Most likely, you know of somewhere nearby that you've "been meaning to get to" for the last X amount of years. A summer Friday is the perfect opportunity to make it happen. It's a relatively inexpensive way to get some of that "different perspective" people are always gushing about after their trips abroad--and you don't even need a passport!

Visiting a neighboring city also has the added bonus of helping you scope out what's going on in your industry, but in another place. You'd be surprised at how much an industry can vary city to city, even if those cities aren't super far from each other. Why not take a (small) step outside of it and see how the other half is doing things? Grab a coffee or lunch with someone in your industry and get to know their space a little more. 

A Local Library

Most of us say in December that we want to read more next year, but how many of us actually do it? Reading, whether it's fiction, non-fiction or something else entirely, is one of the easiest ways to keep the gears turning even when you're away from the office, and the best place to do so is a local library.

I know it doesn't sound exciting--old books, musty air, desktop computers that predate the iPhone--but something about the local library always brings me back to being a kid, when the world still felt big. The jadedness of adulthood is no match for that childlike wonder, and that wonder is something you can bring back to the office on days when work drags a little or things start to feel mundane.

So plop down in an armchair and get to reading (even if it's on a Kindle) and get lost. When you return to reality, you'll be ready to get back to work.
