Celebrating proficiency or development of a skill is important not only to give yourself time to reflect but also record your achievements and showcase to others in your network what you have been developing on. Sometimes, it can be difficult to showcase this especially with hard skills if it is quite a wide topic. For example, you might use Adobe Photoshop to create an poster, or maybe you've used excel to record data.
How can you show others that you have the skills to use a program or piece of software?
Sure, you can use a portfolio or show a project file but sometimes being able to show a accreditation is important to show that you understand the software or application, not just achieve what you set out to do.
A great way to do this is to complete personal development sessions which can award you with certifications for that area to display on profiles such as LinkedIn.
