When looking for new gigs, clients, and jobs, proof of work is one of your best friends.
This combined with a recommendation from a trusted source will almost always help you win new clients, get new gigs, and job offers from your dream companies.
In most cases except the medical field or a few scientific specializations, you don’t even need a degree if you have proof of work.
That’s why you must show and not just tell.
Show that you are able to do what you say in your portfolio or resume.
You can build a prototype to show what you can do or in some cases even record a video showing your capabilities.
Bonus points if you get those who have benefited from your work to vouch for you.
