Skill is good and educational certificate is also good. Having any of them can actually put food on your table, but the question is which of them will you let go for the other. I mean education can get you a white collar job the same way a skill can too. For me i will let go of the skill because skill without basic education is not good at all. Because I have seen a situation whereby a guy with good skill who got a job was unable to give quotation and he lost the job .Formal education is good for everyone.
I think education and skill are both significant and in the modern world, skill often proves to be much more useful as it demonstrates what a particular person can do. A certificate may bring you into the room but your competence is what will sustain you there Having said that, at the same time basic education is required as it assists you in communicating correctly and dealing with professional scenarios. In my case, I would place a priority in skill but still keep education as a sustenance since when both are combined, a person is stronger in the long term.
