In recent years, we've seen more and more designers who choose to specialize in one aspect of design, yet they also choose to continue investing in their education.

Perhaps you could learn digital marketing or take up videography.
This works in tandem with Point 01. Invest in your knowledge, skills and work flow. These are the keys to your success - no matter what anyone tells you. To go a step a further, we encourage you to share what you know. This could take many contexts; whether that's using your knowledge of contrast to help a friend uplift their living room or just simply advising what works best for Wild West themed Steak restaurant.
