If you work in a role where you tend to see a lull in your workload at the end of the year approaches, you may be looking for an extra outlet to channel your energy. This could mean having a chance to focus on a particular hobby or much-needed relaxation time. Or, it could mean deciding to take on a second job or side project.

While a side project or freelancing opportunities may seem like a lot when you also factor in a full-time job, they’re becoming more and more common and for good reason. It’s a great way to dedicate time to your passions while also bringing in some extra cash or expanding your skillset.

If you’re considering taking on a second job or side project, here are three ways to find success:

Map out your goals

As you start to think about taking on a freelancing opportunity or side project, consider what you’re hoping to accomplish. While it could be something simple like earning extra money, these projects can also help you work towards your long-term career goals. For example, it can lead you to explore other industries or expand your network. Regardless of your intentions, having a clear picture of what you’re hoping to achieve is a great way to hone in on the right opportunities for you.

Check your employment terms

Before you fully dive into a second job or side project, check your employment contract to make sure you’re not violating a non-compete or any clause that prohibits you from doing similar work for other clients. Doing so can have harsh consequences, such as getting fired or even sued. Even if this isn’t the case, you may want to run it by your supervisor anyway. Being transparent can go a long way in their eyes, and they may even see potential freelance opportunities or a side project as an opportunity for more professional growth.

Set a limit on how much time your side project gets

It should go without saying, but your side project shouldn’t take away from your productivity at your full-time role. In order to prevent your priorities your priorities from getting tangled, go into your side project with a hard limit on how much time you will devote to your side gig. Perhaps you give your side gig a looser set of guidelines, such as only working on weekends, or during certain hours per week. Regardless of what you decide, never do your freelance work on your employer’s time. If you can’t meet your expectations or be fully present at work, you might need to cut back on your freelancing hours or project.
