Retail will take anyone and train them which is why it is so easy.

Every other job needs someone with special skills and so they are selective and hard to get in. Even though most people don't work retails, there is much more competition for these jobs, and a lot less job in any given specialty. The better the job the less competition there is - but there still is plenty of competition.

Which means you need to not ask for "a job", but select the specific job and then set yourself up to be good at that on your own time. The more specialized you get, the better a chance you have a job in that specialty - but the worse chance you get at any other job! Which means choosing the right specialty is critically important. Good luck (usually it too bad though as most things have enough demand).

The worst part: once you get a job they start teaching you the skill for that. It is really hard to change latter because you go from an expert to beginner.

Remember what others have said though: who you know is more important that what you know! So figure out who you know! Figure out what they can maybe get you into, and apply the above in consideration of that. Sometimes people will tell you what they can help you with, sometimes they won't know but you can guess.
